##Close button 

close button for dismissing content like modals and alerts.
Provide an option to dismiss or close a component with .btn-close. Default styling is limited, but highly customizable. Modify the Sass variables to replace the default background-image. Be sure to include text for screen readers, as we’ve done with aria-label.

```
<button type="button" class="btn-close" aria-label="Close"></button>
```

**Disable state**

Disabled close buttons change their opacity. We’ve also applied pointer-events: none and user-select: none to preventing hover and active states from triggering.

```
<button type="button" class="btn-close" disabled aria-label="Close"></button>
```

**White variant**

Change the default .btn-close to be white with the .btn-close-white class. This class uses the filter property to invert the background-image.

```
<button type="button" class="btn-close btn-close-white" aria-label="Close"></button>
<button type="button" class="btn-close btn-close-white" disabled aria-label="Close"></button>
```

**Collapse**

Collapse is a vertical element used to show and hide content via class changes.

Toggle the visibility of content across your project with a few classes and our JavaScript plugins.

**How it works**

The collapse JavaScript plugin is used to show and hide content. Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the height from its current value to 0. Given how CSS handles animations, you cannot use padding on a .collapse element. Instead, use the class as an independent wrapping element.

**Basic example**

Click the buttons below to show and hide another element via class changes:

•	.collapse hides content

•	.collapsing is applied during transitions

•	.collapse.show shows content

You can use a link with the href attribute, or a button with the data-bs-target attribute. In both cases, the data-bs-toggle="collapse" is required.

```
<!-- Buttons trigger collapse -->
<p>
  <a class="btn btn-primary" data-bs-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
    Link with href
  </a>
  <button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
    Button with data-bs-target
  </button>
</p>
<div class="collapse" id="collapseExample">
  <div class="card card-body">
    Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
  </div>
</div>
```

**Multiple targets**

A `<button>` or `<a>` can show and hide multiple elements by referencing them with a selector in its href or data-bs-target attribute. Multiple `<button>` or `<a>` can show and hide an element if they each reference it with their href or data-bs-target attribute

<!-- Buttons trigger collapse -->
<a class="btn btn-primary" data-bs-toggle="collapse" href="#multiCollapseExample1" role="button"
            aria-expanded="false" aria-controls="multiCollapseExample1">Toggle first element</a>
        <button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target="#multiCollapseExample2"
            aria-expanded="false" aria-controls="multiCollapseExample2">Toggle second element</button>
        <button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target=".multi-collapse"
            aria-expanded="false" aria-controls="multiCollapseExample1 multiCollapseExample2">Toggle both
            elements</button>
        <div class="row">
            <div class="col">
                <div class="collapse multi-collapse" id="multiCollapseExample1">
                    <div class="card card-body">
                        Some placeholder content for the first collapse component of this multi-collapse example. This
                        panel is hidden by default but revealed when the user activates the relevant trigger.
                    </div>
                </div>
            </div>
            <div class="col">
                <div class="collapse multi-collapse" id="multiCollapseExample2">
                    <div class="card card-body">
                        Some placeholder content for the second collapse component of this multi-collapse example. This
                        panel is hidden by default but revealed when the user activates the relevant trigger.
                    </div>
                </div>
            </div>
        </div>
```

**List group**
 
List groups are responsive components for displaying a series of content. A beautiful alternative to unordered lists.

List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fm4hcpf5lziuihoxaqvo.png)
```
<ul class="list-group">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>
```

**Active items**

Add .active to a .list-group-item to indicate the current active selection.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gkbi2516pgd62t3s0wyr.png)
```
<ul class="list-group">
  <li class="list-group-item active" aria-current="true">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>
```

**Disabled items**

Add .disabled to a .list-group-item to make it appear disabled. Note that some elements with .disabled will also require custom JavaScript to fully disable their click events (e.g., links).
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/02rwz0x5z17o6nc0p9r2.png)
```
<ul class="list-group">
  <li class="list-group-item disabled" aria-disabled="true">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>
```

**Links and buttons**

Use `<a>`s or `<button>`s to create actionable list group items with hover, disabled, and active states by adding .list-group-item-action. We separate these pseudo-classes to ensure list groups made of non-interactive elements (like `<li>`s or `<div>`s) don’t provide a click or tap affordance.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tm3df0bg6wqk0ck2s4xq.png)
```
<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active" aria-current="true">
    Cras justo odio
  </a>
  <a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>
  <a href="#" class="list-group-item list-group-item-action">Morbi leo risus</a>
  <a href="#" class="list-group-item list-group-item-action">Porta ac consectetur ac</a>
  <a
    href="#"
    class="list-group-item list-group-item-action disabled"
    tabindex="-1"
    aria-disabled="true"
    >Vestibulum at eros</a
  >
</div>
```

**Buttons**

With <button>s, you can also make use of the disabled attribute instead of the .disabled class. Sadly, <a>s don’t support the disabled attribute.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7e86932ugbc8s8ws89lb.png)
```
<div class="list-group">
  <button
    type="button"
    class="list-group-item list-group-item-action active"
    aria-current="true"
  >
    Cras justo odio
  </button>
  <button type="button" class="list-group-item list-group-item-action">
    Dapibus ac facilisis in
  </button>
  <button type="button" class="list-group-item list-group-item-action">
    Morbi leo risus
  </button>
  <button type="button" class="list-group-item list-group-item-action">
    Porta ac consectetur ac
  </button>
  <button type="button" class="list-group-item list-group-item-action" disabled>
    Vestibulum at eros
  </button>
</div>
```

**Flush**

Add .list-group-flush to remove some borders and rounded corners to render list group items edge-to-edge in a parent container (e.g., cards).
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/krmq8bx0ex8etyanfu9r.png)
```
<ul class="list-group list-group-flush">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>
```

**Horizontal**

Add .list-group-horizontal to change the layout of list group items from vertical to horizontal across all breakpoints. Alternatively, choose a responsive variant .list-group-horizontal-{sm|md|lg|xl|xxl} to make a list group horizontal starting at that breakpoint’s min-width. Currently horizontal list groups cannot be combined with flush list groups.

```
<ul class="list-group list-group-horizontal">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
<ul class="list-group list-group-horizontal-sm">
  <li class="list-group-item">Cras justo odio</li>

  <li class="list-group-item">Morbi leo risus</li>
</ul>
<ul class="list-group list-group-horizontal-md">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
<ul class="list-group list-group-horizontal-lg">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
<ul class="list-group list-group-horizontal-xl">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
<ul class="list-group list-group-horizontal-xxl">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
</ul>
```

**Contextual classes**

Use contextual classes to style list items with a stateful background and color.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mzv6o3ds8zi0wrybl0da.png)
```
<ul class="list-group">
  <li class="list-group-item">Dapibus ac facilisis in</li>

  <li class="list-group-item list-group-item-primary">
    A simple primary list group item
  </li>
  <li class="list-group-item list-group-item-secondary">
    A simple secondary list group item
  </li>
  <li class="list-group-item list-group-item-success">
    A simple success list group item
  </li>
  <li class="list-group-item list-group-item-danger">A simple danger list group item</li>
  <li class="list-group-item list-group-item-warning">
    A simple warning list group item
  </li>
  <li class="list-group-item list-group-item-info">A simple info list group item</li>
  <li class="list-group-item list-group-item-light">A simple light list group item</li>
  <li class="list-group-item list-group-item-dark">A simple dark list group item</li>
</ul>
```

**Badges**

Add badges to any list group item to show unread counts, activity, and more with the help of some flexbox utilities.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sv9ekd0hemw0t34hsl4d.png)
```
<ul class="list-group">
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Cras justo odio
    <span class="badge bg-primary rounded-pill">14</span>
  </li>
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Dapibus ac facilisis in
    <span class="badge bg-primary rounded-pill">2</span>
  </li>
  <li class="list-group-item d-flex justify-content-between align-items-center">
    Morbi leo risus
    <span class="badge bg-primary rounded-pill">1</span>
  </li>
</ul>
```

**Custom content**

Add nearly any HTML within, even for linked list groups like the one below, with the help of flexbox utilities.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/l9d7xsg2h8dsyljiv5l8.png)
```
<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active" aria-current="true">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small>3 days ago</small>
    </div>
    <p class="mb-1">
      Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus
      varius blandit.
    </p>
    <small>Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small class="text-muted">3 days ago</small>
    </div>
    <p class="mb-1">
      Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus
      varius blandit.
    </p>
    <small class="text-muted">Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5 class="mb-1">List group item heading</h5>
      <small class="text-muted">3 days ago</small>
    </div>
    <p class="mb-1">
      Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus
      varius blandit.
    </p>
    <small class="text-muted">Donec id elit non mi porta.</small>
  </a>
</div>
```


**JavaScript behavior**

Use the tab JavaScript plugin to extend our list group to create tabbable panes of local content.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kxqi4tmorvxyslevljuf.png)
```
 <div class="row">
            <div class="col-4">
              <div class="list-group" id="list-tab" role="tablist">
                <a class="list-group-item list-group-item-action active" id="list-home-list" data-bs-toggle="list" href="#list-home" role="tab" aria-controls="list-home">Home</a>
                <a class="list-group-item list-group-item-action" id="list-profile-list" data-bs-toggle="list" href="#list-profile" role="tab" aria-controls="list-profile">Profile</a>
                <a class="list-group-item list-group-item-action" id="list-messages-list" data-bs-toggle="list" href="#list-messages" role="tab" aria-controls="list-messages">Messages</a>
                <a class="list-group-item list-group-item-action" id="list-settings-list" data-bs-toggle="list" href="#list-settings" role="tab" aria-controls="list-settings">Settings</a>
              </div>
            </div>
            <div class="col-8">
              <div class="tab-content" id="nav-tabContent">
                <div class="tab-pane fade show active" id="list-home" role="tabpanel" aria-labelledby="list-home-list">...</div>
                <div class="tab-pane fade" id="list-profile" role="tabpanel" aria-labelledby="list-profile-list">...</div>
                <div class="tab-pane fade" id="list-messages" role="tabpanel" aria-labelledby="list-messages-list">...</div>
                <div class="tab-pane fade" id="list-settings" role="tabpanel" aria-labelledby="list-settings-list">...</div>
              </div>
            </div>
          </div>
```

**Fade effect**

To make tabs panel fade in, add .fade to each .tab-pane. The first tab pane must also have .show to make the initial content visible.
```
<div class="tab-content">
  <div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
</div>
```


###Dropdowns 

Dropdowns are responsible for toggleable (collapsible) display a list of links.

**Basic examples**

Wrap the dropdown’s toggle (your button or link) and the dropdown menu within .dropdown, or another element that declares position: relative;. Dropdowns can be triggered from `<a>` or `<button>` elements to better fit your potential needs. The examples shown here use semantic `<ul>` elements where appropriate, but custom markup is supported.

**Regular button**

Any single .btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either `<button>` elements:

```
<div class="dropdown">
  <button
    class="btn btn-primary dropdown-toggle"
    type="button"
    id="dropdownMenuButton"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropdown button
  </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>
```

**Link button**
And with `<a>` elements:
```
<div class="dropdown">
  <a
    class="btn btn-primary dropdown-toggle"
    href="#"
    role="button"
    id="dropdownMenuLink"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropdown link
  </a>

  <ul class="dropdown-menu" aria-labelledby="dropdownMenuLink">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>
```

**Colors**

You can do this with any button variant:
```
<!-- Primary -->
<div class="btn-group">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Action
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li>
      <hr class="dropdown-divider" />
    </li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

<!-- Secondary -->

    Action
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>

    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li>
      <hr class="dropdown-divider" />

  </ul>
</div>

    class="btn btn-success dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"

    <li>
      <hr class="dropdown-divider" />
    </li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>

**Split button**

Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-split for proper spacing around the dropdown caret.

We use this extra class to reduce the horizontal padding on either side of the caret by 25% and remove the margin-left that’s added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.
```
<!-- Example split primary button -->
<div class="btn-group">
  <button type="button" class="btn btn-primary">Action</button>
  <button
    type="button"
    class="btn btn-primary dropdown-toggle dropdown-toggle-split"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    <span class="visually-hidden">Toggle Dropdown</span>
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>
```

**Sizing**

Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.
```
<!-- Large button groups (default and split) -->
<div class="btn-group">
  <button
    class="btn btn-primary btn-lg dropdown-toggle"
    type="button"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Large button
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>
<div class="btn-group">
  <button class="btn btn-primary btn-lg" type="button">Large split button</button>
  <button
    type="button"
    class="btn btn-lg btn-primary dropdown-toggle dropdown-toggle-split"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    <span class="visually-hidden">Toggle Dropdown</span>

    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

<!-- Small button groups (default and split) -->
<div class="btn-group">
  <button
    class="btn btn-primary btn-sm dropdown-toggle"
    type="button"
    data-bs-toggle="dropdown"
    aria-expanded="false"

```
<!-- Default dropright button -->
<div class="btn-group dropend">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropright
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

<!-- Split dropright button -->
<div class="btn-group dropend">
  <button type="button" class="btn btn-primary">Split dropright</button>
  <button
    type="button"
    class="btn btn-primary dropdown-toggle dropdown-toggle-split"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    <span class="visually-hidden">Toggle Dropright</span>
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>
```

**Dropleft**

Trigger dropdown menus at the left of the elements by adding .dropstart to the parent element.
```
<!-- Default dropleft button -->
<div class="btn-group dropstart">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropleft
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider" /></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

<!-- Split dropleft button -->
<div class="btn-group">
  <div class="btn-group dropstart" role="group">
    <button
      type="button"
      class="btn btn-primary dropdown-toggle dropdown-toggle-split"
      data-bs-toggle="dropdown"
      aria-expanded="false"
    >
      <span class="visually-hidden">Toggle Dropleft</span>
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider" /></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
  </div>
  <button type="button" class="btn btn-primary">Split dropleft</button>
</div>
```

**Menu items**

Historically dropdown menu contents had to be links, but that’s no longer the case with v4. Now you can optionally use `<button>` elements in your dropdowns instead of just `<a>`.
```
<div class="dropdown">
  <button
    class="btn btn-primary dropdown-toggle"
    type="button"
    id="dropdownMenu2"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropdown
  </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenu2">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li>
      <button class="dropdown-item" type="button">Another action</button>
    </li>
    <li>
      <button class="dropdown-item" type="button">Something else here</button>
    </li>
  </ul>
</div>
```

You can also create non-interactive dropdown items with .dropdown-item-text. Feel free to style further with custom CSS or text utilities.
```
<ul class="dropdown-menu">
  <li><span class="dropdown-item-text">Dropdown item text</span></li>
  <li><a class="dropdown-item" href="#">Action</a></li>
  <li><a class="dropdown-item" href="#">Another action</a></li>
  <li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>
```

**Active**

Add .active to items in the dropdown to style them as active. To convey the active state to assistive technologies, use the aria-current attribute — using the page value for the current page, or true for the current item in a set.
```
<ul class="dropdown-menu">
  <li><a class="dropdown-item" href="#">Regular link</a></li>
  <li>
    <a class="dropdown-item active" href="#" aria-current="true">Active link</a>
  </li>
  <li><a class="dropdown-item" href="#">Another link</a></li>
</ul>
```

**Disabled**

Add .disabled to items in the dropdown to style them as disabled.
```
<ul class="dropdown-menu">
  <li><a class="dropdown-item" href="#">Regular link</a></li>
  <li>
    <a class="dropdown-item disabled" href="#" tabindex="-1" aria-disabled="true"
      >Disabled link</a
    >
  </li>
  <li><a class="dropdown-item" href="#">Another link</a></li>
</ul>
```

**Menu alignment**

By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add .dropdown-menu-end to a .dropdown-menu to right align the dropdown menu.
```
<div class="btn-group">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Right-aligned menu
  </button>
  <ul class="dropdown-menu dropdown-menu-end">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li>
      <button class="dropdown-item" type="button">Another action</button>
    </li>
    <li>
      <button class="dropdown-item" type="button">Something else here</button>
    </li>
  </ul>
</div>
```

**Responsive alignment**

If you want to use responsive alignment, disable dynamic positioning by adding the data-bs-display="static" attribute and use the responsive variation classes.

To align right the dropdown menu with the given breakpoint or larger, add .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-end.
```
<div class="btn-group">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    data-bs-display="static"
    aria-expanded="false"
  >
    Left-aligned but right aligned when large screen
  </button>
  <ul class="dropdown-menu dropdown-menu-lg-end">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li>
      <button class="dropdown-item" type="button">Another action</button>
    </li>
    <li>
      <button class="dropdown-item" type="button">Something else here</button>
    </li>
  </ul>
</div>
```

To align left the dropdown menu with the given breakpoint or larger, add .dropdown-menu-end and .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-start.
```
<div class="btn-group">
  <button
    type="button"
    class="btn btn-primary dropdown-toggle"
    data-bs-toggle="dropdown"
    data-bs-display="static"
    aria-expanded="false"
  >
    Right-aligned but left aligned when large screen
  </button>
  <ul class="dropdown-menu dropdown-menu-end dropdown-menu-lg-start">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li>
      <button class="dropdown-item" type="button">Another action</button>
    </li>
    <li>
      <button class="dropdown-item" type="button">Something else here</button>
    </li>
  </ul>
</div>
```

**Alignment options**

Taking most of the options shown above, here’s a small kitchen sink demo of various dropdown alignment options in one place.
```
<div class="btn-group">
  <button
    class="btn btn-secondary dropdown-toggle"
    type="button"
    id="dropdownMenuButton"
    data-bs-toggle="dropdown"

    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
  </ul>
</div>

<div class="btn-group">
  <button
    type="button"
    class="btn btn-secondary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Right-aligned menu
  </button>
  <ul class="dropdown-menu dropdown-menu-end">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>

    data-bs-toggle="dropdown"
    data-bs-display="static"
    aria-expanded="false"

    Left-aligned, right-aligned lg
  </button>
  <ul class="dropdown-menu dropdown-menu-lg-end">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
  </ul>
</div>

<div class="btn-group">

    type="button"
    class="btn btn-secondary dropdown-toggle"
    data-bs-toggle="dropdown"
    data-bs-display="static"
    aria-expanded="false"

    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
  </ul>
</div>

<div class="btn-group dropstart">
  <button
    type="button"
    class="btn btn-secondary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropstart

  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
  </ul>
</div>

<div class="btn-group dropend">
  <button
    type="button"
    class="btn btn-secondary dropdown-toggle"
    data-bs-toggle="dropdown"
    aria-expanded="false"
  >
    Dropend
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
  </ul>
</div>
```

###Menu content

**Headers**

Add a header to label sections of actions in any dropdown menu.
```
<ul class="dropdown-menu">
  <li><h6 class="dropdown-header">Dropdown header</h6></li>
  <li><a class="dropdown-item" href="#">Action</a></li>
  <li><a class="dropdown-item" href="#">Another action</a></li>
</ul>
```

**Dividers**

Separate groups of related menu items with a divider.
```
<ul class="dropdown-menu">
  <li><a class="dropdown-item" href="#">Action</a></li>
  <li><a class="dropdown-item" href="#">Another action</a></li>
  <li><a class="dropdown-item" href="#">Something else here</a></li>
  <li><hr class="dropdown-divider" /></li>
  <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
```

**Text**

Place any freeform text within a dropdown menu with text and use spacing utilities. Note that you’ll likely need additional sizing styles to constrain the menu width.
[text]
```
<div class="dropdown-menu p-4 text-muted" style="max-width: 200px">
  <p>Some example text that's free-flowing within the dropdown menu.</p>
  <p class="mb-0">And this is more example text.</p>
</div>
```

##Pagination

Pagination indicates a series of related content exists across multiple pages.

**Overview**
We use a large block of connected links for our pagination, making links hard to miss and easily scalable—all while providing large hit areas. Pagination is built with list HTML elements so screen readers can announce the number of available links. Use a wrapping <nav> element to identify it as a navigation section to screen readers and other assistive technologies.

In addition, as pages likely have more than one such navigation section, it’s advisable to provide a descriptive aria-label for the <nav> to reflect its purpose. 

For example, if the pagination component is used to navigate between a set of search results, an appropriate label could be aria-label="Search results pages".

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bx7pdhjjtm4z4gmluo36.png)
```
<nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item"><a class="page-link" href="#">Previous</a></li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item"><a class="page-link" href="#">Next</a></li>
  </ul>
</nav>
```

**Working with icons**

Looking to use an icon or symbol in place of text for some pagination links? Be sure to provide proper screen reader support with aria attributes.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sdektwspqqw85pmlp64p.png)
```
 <nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Previous">
        <span aria-hidden="true">&laquo;</span>
      </a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Next">
        <span aria-hidden="true">&raquo;</span>
      </a>
    </li>
  </ul>
</nav>
```

**Disabled and active states**

Pagination links are customizable for different circumstances. Use .disabled for links that appear un-clickable and .active to indicate the current page.

While the .disabled class uses pointer-events: none to try to disable the link functionality of `<a>`s, that CSS property is not yet standardized and doesn’t account for keyboard navigation. As such, you should always add tabindex="-1" on disabled links and use custom JavaScript to fully disable their functionality.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2u1wemqzkgt6b420d5my.png)
```
<nav aria-label="...">
  <ul class="pagination">
    <li class="page-item disabled">
      <a class="page-link" href="#" tabindex="-1" aria-disabled="true">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item active" aria-current="page">
      <a class="page-link" href="#">2</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>
```

You can optionally swap out active or disabled anchors for <span>, or omit the anchor in the case of the prev/next arrows, to remove click functionality and prevent keyboard focus while retaining intended styles.

**Sizing**

Fancy larger or smaller pagination? Add .pagination-lg or .pagination-sm for additional sizes.

**Popovers**

Popover is like a tooltip, but it can persist after hovering off. It allows displaying more content including header & footer.
```
<button
  type="button"
  class="btn btn-lg btn-danger"
  data-bs-toggle="popover"
  title="Popover title"
  data-bs-content="And here's some amazing content. It's very engaging. Right?"
>
  Click to toggle popover
</button>
```

**Overview**

Things to know when using the popovers:

•	Popovers are opt-in for performance reasons, so you must initialize them yourself.

•	Zero-length title and content values will never show a popover.

•	Specify container: 'body' to avoid rendering problems in more complex components (like our input groups, button groups, etc).

•	Triggering popovers on hidden elements will not work.

•	Popovers for .disabled or disabled elements must be triggered on a wrapper element.

•	When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors’ overall width. Use .text-nowrap on your `<a>`s to avoid this behavior.

•	Popovers must be hidden before their corresponding elements have been removed from the DOM.

•	Popovers can be triggered thanks to an element inside a shadow DOM.

**Four directions**

Four options are available: top, right, bottom, and left aligned.
```
<button
  type="button"
  class="btn btn-secondary"
  data-bs-container="body"
  data-bs-toggle="popover"
  data-bs-placement="top"
  data-bs-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
>
  Popover on top
</button>

<button
  type="button"
  class="btn btn-secondary"
  data-bs-container="body"
  data-bs-toggle="popover"
  data-bs-placement="right"
  data-bs-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
>
  Popover on right
</button>

<button
  type="button"
  class="btn btn-secondary"
  data-bs-container="body"
  data-bs-toggle="popover"
  data-bs-placement="bottom"
  data-bs-content="Vivamus
sagittis lacus vel augue laoreet rutrum faucibus."
>
  Popover on bottom
</button>

<button
  type="button"
  class="btn btn-secondary"
  data-bs-container="body"
  data-bs-toggle="popover"
  data-bs-placement="left"
  data-bs-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
>
  Popover on left
</button>
```

**Dismiss on next click**

Use the focus trigger to dismiss popovers on the user’s next click of a different element than the toggle element.
```
<a
  tabindex="0"
  class="btn btn-lg btn-danger"
  role="button"
  data-bs-toggle="popover"
  data-bs-trigger="focus"
  title="Dismissible popover"
  data-bs-content="And here's some amazing content. It's very engaging. Right?"
  >Dismissible popover</a>
```

**Disabled elements**

Elements with the disabled attribute aren’t interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you’ll want to trigger the popover from a wrapper <div> or <span> and override the pointer-events on the disabled element.

For disabled popover triggers, you may also prefer data-bs-trigger="hover" so that the popover appears as immediate visual feedback to your users as they may not expect to click on a disabled element.
```
<span
  class="d-inline-block"
  data-bs-toggle="popover"
  data-bs-content="Disabled popover"
>
  <button class="btn btn-primary" style="pointer-events: none" type="button" disabled>
    Disabled button
  </button>
</span>
```

**Modal**
 
Modal is a responsive popup used to display extra content. That includes prompts, configurations, cookie consents, etc.
```
<!-- Button trigger modal -->
<button
  type="button"
  class="btn btn-primary"
  data-bs-toggle="modal"
  data-bs-target="#exampleModal"
>
  Launch demo modal
</button>

<!-- Modal -->
<div
  class="modal fade"
  id="exampleModal"
  tabindex="-1"
  aria-labelledby="exampleModalLabel"
  aria-hidden="true"
>
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button
          type="button"
          class="btn-close"
          data-bs-dismiss="modal"
          aria-label="Close"
        ></button>
      </div>
      <div class="modal-body">...</div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">
          Close
        </button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
```

**Advanced examples**

Click the buttons to launch the modals.
**How it works**

Before getting started with bs modal component, be sure to read the following as our menu options have recently changed.

•	Modals are built with HTML, CSS, and JavaScript. They’re positioned over everything else in the document and remove scroll from the <body> so that modal content scrolls instead.

•	Clicking on the modal “backdrop” will automatically close the modal.

•	Bootstrap only supports one modal window at a time. Nested modals aren’t supported as we believe them to be poor user experiences.

•	Modals use position: fixed, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You’ll likely run into issues when nesting a .modal within another fixed element.

•	Once again, due to position: fixed, there are some caveats with using modals on mobile devices.

•	Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:
```
const myModal = document.getElementById('myModal')
const myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', () => {
  myInput.focus()
})
```

**Modal components**

Below is a static modal example (meaning its position and display have been overridden). Included are the modal header, modal body (required for padding), and modal footer (optional). We ask that you include modal headers with dismiss actions whenever possible, or provide another explicit dismiss action.
```
<div class="modal" tabindex="-1">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Modal title</h5>
        <button
          type="button"
          class="btn-close"
          data-bs-dismiss="modal"
          aria-label="Close"
        ></button>
      </div>
      <div class="modal-body">
        <p>Modal body text goes here.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">
          Close
        </button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
```

**Static backdrop**

When backdrop is set to static, the modal will not close when clicking outside it. 
```
<!-- Button trigger modal -->
<button
  type="button"
  class="btn btn-primary"
  data-bs-toggle="modal"
  data-bs-target="#staticBackdrop"
>
  Launch static backdrop modal
</button>

<!-- Modal -->
<div
  class="modal fade"
  id="staticBackdrop"
  data-bs-backdrop="static"
  data-bs-keyboard="false"
  tabindex="-1"
  aria-labelledby="staticBackdropLabel"
  aria-hidden="true"
>
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="staticBackdropLabel">Modal title</h5>
        <button
          type="button"
          class="btn-close"
          data-bs-dismiss="modal"
          aria-label="Close"
        ></button>
      </div>
      <div class="modal-body">...</div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">
          Close
        </button>
        <button type="button" class="btn btn-primary">Understood</button>
      </div>
    </div>
  </div>
</div>
```

###Navbar

Bootstrap’s powerful, responsive navigation header, the navbar. Includes support for branding, navigation, and more, including support for our collapse plugin.

**How it works**

Here’s what you need to know before getting started with the navbar:

•	Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl|-xxl} for responsive collapsing and color scheme classes.

•	Navbars and their contents are fluid by default. Change the container to limit their horizontal width in different ways.

•	Use our spacing and flex utility classes for controlling spacing and alignment within navbars.

•	Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.

•	Ensure accessibility by using a <nav> element or, if using a more generic element such as a <div>, add a role="navigation" to every navbar to explicitly identify it as a landmark region for users of assistive technologies.

•	Indicate the current item by using aria-current="page" for the current page or aria-current="true" for the current item in a set.


**Supported content**

Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:

•	.navbar-brand for your company, product, or project name.

•	.navbar-nav for a full-height and lightweight navigation (including support for dropdowns).

•	.navbar-toggler for use with our collapse plugin and other navigation toggling behaviors.

•	Flex and spacing utilities for any form controls and actions.

•	.navbar-text for adding vertically centered strings of text.

•	.collapse.navbar-collapse for grouping and hiding navbar contents by a parent breakpoint.

•	Add an optional .navbar-scroll to set a max-height and scroll expanded navbar content.

Here’s an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the lg (large) breakpoint.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ujya91uvt05ect6e4cgt.png)
```
<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Dropdown
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>
```

This example uses background (bg-light) and spacing (my-2, my-lg-0, me-sm-0, my-sm-0) utility classes.

**Brand**

The .navbar-brand can be applied to most elements, but an anchor works best, as some elements might require utility classes or custom styles.

**Text**

Add your text within an element with the .navbar-brand class.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/m217lve1ty1nzxbxt1b0.png)
```
<!-- As a link -->
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
  </div>
</nav>

<!-- As a heading -->
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <span class="navbar-brand mb-0 h1">Navbar</span>
  </div>
</nav>
```

**Image**

You can replace the text within the .navbar-brand with an <img>.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xehg3oasoct56u3noi7z.png)
```
<nav class="navbar navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">
      <img src="/docs/5.0/assets/brand/bootstrap-logo.svg" alt="" width="30" height="24">
    </a>
  </div>
</nav>
```

**Image and text**

You can also make use of some additional utilities to add an image and text at the same time. Note the addition of .d-inline-block and .align-text-top on the <img>.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sq1pnrvg5fywxepo99wc.png)
```
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">
      <img src="/docs/5.0/assets/brand/bootstrap-logo.svg" alt="" width="30" height="24" class="d-inline-block align-text-top">
      Bootstrap
    </a>
  </div>
</nav>
```

**Nav**

Navbar navigation links build on our .nav options with their own modifier class and require the use of toggler classes for proper responsive styling. Navigation in navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents securely aligned.

Add the .active class on .nav-link to indicate the current page.
Please note that you should also add the aria-current attribute on the active .nav-link.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/i4387pbu23i4xtt26nyn.png)
```
<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
    </div>
  </div>
</nav>
```

**Forms**

Place various form controls and components within a navbar:
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qg04z48sims3o02mhh7r.png)
```
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>
  </div>
</nav>
```

Immediate child elements of .navbar use flex layout and will default to justify-content: space-between. Use additional flex utilities as needed to adjust this behavior.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ds50zxe5g147g8ajd38l.png)
```
  <nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand">Navbar</a>
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>
  </div>
</nav>
```

Input groups work, too. If your navbar is an entire form, or mostly a form, you can use the <form> element as the container and save some HTML.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qy398igmo8dk6x3vndq8.png)
```
<nav class="navbar navbar-light bg-light">
  <form class="container-fluid">
    <div class="input-group">
      <span class="input-group-text" id="basic-addon1">@</span>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </div>
  </form>
</nav>
```

Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7a5ypixb8qrg17io99y9.png)
```  
<nav class="navbar navbar-light bg-light">
  <form class="container-fluid justify-content-start">
    <button class="btn btn-outline-success me-2" type="button">Main button</button>
    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>
```

**Text**

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kidkcbyzh0y9uqal4kk7.png)
```
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <span class="navbar-text">
      Navbar text with an inline element
    </span>
  </div>
</nav>
```

Mix and match with other components and utilities as needed.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/v7soos1599348hanq5yf.png)
```
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar w/ text</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarText">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      <span class="navbar-text">
        Navbar text with an inline element
      </span>
    </div>
</div>
</nav>
```

**Color schemes**

Theming the navbar has never been easier thanks to the combination of theming classes and background-color utilities. Choose from .navbar-light for use with light background colors, or .navbar-dark for dark background colors. Then, customize with .bg-* utilities.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/b6izcj6o4gjp375apju0.png)
```
<nav class="navbar navbar-dark bg-dark">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-dark bg-primary">

<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
  <!-- Navbar content -->

</nav>
```

**Containers**

Although it’s not required, you can wrap a navbar in a .container to center it on a page–though note that an inner container is still required. Or you can add a container inside the .navbar to only center the contents of a fixed or static top navbar.

```
<div class="container">
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container-fluid">
      <a class="navbar-brand" href="#">Navbar</a>
    </div>
  </nav>
</div>
```

**Placement**

Use our position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the <body>) to prevent overlap with other elements.

Also note that .sticky-top uses position: sticky, which isn’t fully supported in every browser.

  <div class="container-fluid">
    <a class="navbar-brand" href="#">Sticky top</a>
  </div>
</nav>
```

**Scrolling**

Add .navbar-nav-scroll to a .navbar-nav (or other navbar sub-component) to enable vertical scrolling within the toggleable contents of a collapsed navbar. By default, scrolling kicks in at 75vh (or 75% of the viewport height), but you can override that with the local CSS custom property --bs-navbar-height or custom styles. At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.

Please note that this behavior comes with a potential drawback of overflow—when setting overflow-y: auto (required to scroll the content here), overflow-x is the equivalent of auto, which will crop some horizontal content.

Here’s an example navbar using .navbar-nav-scroll with style="--bs-scroll-height: 100px;", with some extra margin utilities for optimum spacing.

 <nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">

    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarScroll" aria-controls="navbarScroll" aria-expanded="false" aria-label="Toggle navigation">

    <div class="collapse navbar-collapse" id="navbarScroll">
      <ul class="navbar-nav me-auto my-2 my-lg-0 navbar-nav-scroll" style="--bs-scroll-height: 100px;">

            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">

        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>
```

**Responsive behaviors**

Navbars can use .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl|-xxl} classes to determine when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

**Toggler**

Navbar togglers are left-aligned by default, but should they follow a sibling element like a .navbar-brand, they’ll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.

With no .navbar-brand shown at the smallest breakpoint:
 
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1q8qgvjb31u1pdajpprn.png)
```
<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
      <a class="navbar-brand" href="#">Hidden brand</a>
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>
```

**External content**

Sometimes you want to use the collapse plugin to trigger a container element for content that structurally sits outside of the .navbar . Because our plugin works on the id and data-bs-target matching, that’s easily done!
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0m4z7konfsz5wdikfloa.png)
```
<div class="collapse" id="navbarToggleExternalContent">
  <div class="bg-dark p-4">
    <h5 class="text-white h4">Collapsed content</h5>
    <span class="text-muted">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>
```

When you do this, we recommend including additional JavaScript to move the focus programmatically to the container when it is opened. Otherwise, keyboard users and users of assistive technologies will likely have a hard time finding the newly revealed content - particularly if the container that was opened comes before the toggler in the document’s structure. 
We also recommend making sure that the toggler has the aria-controls attribute, pointing to the id of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.



###Breadcrumb

Indicate the current page’s location within a navigational hierarchy that automatically adds separators via CSS.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/td18s4ovyz4tvsnyw233.png)
```
<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item active" aria-current="page">Home</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item"><a href="#">Library</a></li>
    <li class="breadcrumb-item active" aria-current="page">Data</li>
  </ol>
```

###Dividers

Dividers are automatically added in CSS through ::before and content. They can be changed by modifying a local CSS custom property --bs-breadcrumb-divider, or through the $breadcrumb-divider Sass variable — and $breadcrumb-divider-flipped for its RTL counterpart, if needed. We default to our Sass variable, which is set as a fallback to the custom property. 

This way, you get a global divider that you can override without recompiling CSS at any time.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ebkxy7jgax17ovsdjx6h.png)
```
<nav style="--bs-breadcrumb-divider: '>';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>
```

When modifying via Sass, the quote function is required to generate the quotes around a string. For example, using > as the divider, you can use this:
```
$breadcrumb-divider: quote(">");
```

It’s also possible to use an embedded SVG icon. Apply it via our CSS custom property, or use the Sass variable.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0bv4e2ta595nu65hmmjl.png)
 ```
<nav style="--bs-breadcrumb-divider: url(&#34;data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E&#34;);" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>


$breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E");
```

You can also remove the divider setting --bs-breadcrumb-divider: ''; (empty strings in CSS custom properties counts as a value), or setting the Sass variable to $breadcrumb-divider: none;.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uiywg4qysekogylfv05r.png)
```
<nav style="--bs-breadcrumb-divider: '';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>


$breadcrumb-divider: none;
```

**Carousel**

Carousel is a slideshow cycling through different elements such as photos, videos, or text. 
```

**How it works**

The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators.

In browsers where the Page Visibility API is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).

Carousels don’t automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they’re not explicitly required. Add and customize as you see fit.

The .active class needs to be added to one of the slides otherwise the carousel will not be visible. Also be sure to set a unique id on the .carousel for optional controls, especially if you’re using multiple carousels on a single page. Control and indicator elements must have a data-bs-target attribute (or href for links) that matches the id of the .carousel element.

###Variations

**Slides only**

Here’s a carousel with slides only. Note the presence of the .d-block and .w-100 on carousel images to prevent browser default image alignment.
```
<div id="carouselExampleSlidesOnly" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img
        src="https://bsootstrap.com/img/new/slides/041.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/042.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/043.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
  </div>
</div>
```

**With controls**

Adding in the previous and next controls:
```
<div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img
        src="https://bsootstrap.com/img/new/slides/041.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/042.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/043.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
  </div>
  <button
    class="carousel-control-prev"
    type="button"
    data-bs-target="#carouselExampleControls"
    data-bs-slide="prev"
  >
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button
    class="carousel-control-next"
    type="button"
    data-bs-target="#carouselExampleControls"
    data-bs-slide="next"
  >
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
```

**With indicators**

You can also add the indicators to the carousel, alongside the controls, too.
```
<div id="carouselExampleIndicators" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button
      type="button"
      data-bs-target="#carouselExampleIndicators"
      data-bs-slide-to="0"
      class="active"
      aria-current="true"
      aria-label="Slide 1"
    ></button>
    <button
      type="button"
      data-bs-target="#carouselExampleIndicators"
      data-bs-slide-to="1"
      aria-label="Slide 2"
    ></button>
    <button
      type="button"
      data-bs-target="#carouselExampleIndicators"
      data-bs-slide-to="2"
      aria-label="Slide 3"
    ></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img
        src="https://bsootstrap.com/img/new/slides/041.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/042.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/043.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
  </div>
  <button
    class="carousel-control-prev"
    type="button"
    data-bs-target="#carouselExampleIndicators"
    data-bs-slide="prev"
  >
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button
    class="carousel-control-next"
    type="button"
    data-bs-target="#carouselExampleIndicators"
    data-bs-slide="next"
  >
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
```

**With captions**

Add captions to your slides easily with the .carousel-caption element within any .carousel-item. They can be easily hidden on smaller viewports, as shown below, with optional display utilities. We hide them initially with .d-none and bring them back on medium-sized devices with .d-md-block.
```
<div id="carouselExampleCaptions" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button
      type="button"
      data-bs-target="#carouselExampleCaptions"
      data-bs-slide-to="0"
      class="active"
      aria-current="true"
      aria-label="Slide 1"
    ></button>
    <button
      type="button"
      data-bs-target="#carouselExampleCaptions"
      data-bs-slide-to="1"
      aria-label="Slide 2"
    ></button>
    <button
      type="button"
      data-bs-target="#carouselExampleCaptions"
      data-bs-slide-to="2"
      aria-label="Slide 3"
    ></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">

      />
      <div class="carousel-caption d-none d-md-block">

**Animation**

Add .carousel-fade to your carousel to animate slides with a fade transition instead of a slide.
```
<div
  id="carouselExampleFade"
  class="carousel slide carousel-fade"
  data-bs-ride="carousel"
>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img
        src="https://bsootstrap.com/img/new/slides/041.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">
      <img
        src="https://bsootstrap.com/img/new/slides/042.jpg"
        class="d-block w-100"
        alt="..."
      />
    </div>
    <div class="carousel-item">

        alt="..."
      />
    </div>
  </div>
  <button
    class="carousel-control-prev"
    data-bs-target="#carouselExampleFade"
    type="button"
    data-bs-slide="prev"
  >
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button
    class="carousel-control-next"
    data-bs-target="#carouselExampleFade"
    type="button"
    data-bs-slide="next"
  >
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
```

**Dark variant**

Add .carousel-dark to the .carousel for darker controls, indicators, and captions.
```
<!-- Carousel wrapper -->
<div
  id="carouselDarkVariant"
  class="carousel slide carousel-fade carousel-dark"
  data-bs-ride="carousel"
