______

## Installation

#### Manual installation (zip package)

To take advantage of  our Bootstrap images component and use them in your project, you first need to install the [MDB 5 Free package](https://mdbootstrap.com/docs/standard/getting-started/installation/#section-manual-installation)

_______

#### MDB CLI

Watch our [**Quick Start Tutorial**](https://mdbootstrap.com/docs/standard/getting-started/quick-start/) to discover and use the full potential of MDB 5 and MDB CLI

_______

#### NPM

###### Prerequisites

Before starting the project make sure to install [Node LTS (12.x.x recommended)](https://nodejs.org/en/).

###### Installation

To install MDB UI KIT in your project easily type the following command in the terminal:
```terminal
npm i mdb-ui-kit 
```

###### Importing JS modules

You can import the entire library or just individual modules:
```terminal
import * as mdb from 'mdb-ui-kit'; // lib
import { Input } from 'mdb-ui-kit'; // module 
```

###### Importing CSS file

To import MDB stylesheet please use the following syntax:
```terminal
@import '~mdb-ui-kit/css/mdb.min.css'; 
```

###### Importing SCSS modules

You can also import individual SCSS modules. To do it properly, we recommend to copy them from the node_modules/mdb-ui-kit/src/scss location directly to your project and import in the same way as CSS files.

###### Webpack integration

You can significantly speed up the process of creating a new project based on Webpack using our [Starter](https://github.com/mdbootstrap/mdb-webpack-starter).

__________

#### CDN

Installation via CDN is one of the easiest methods of integrating MDB UI KIT with your project. Just copy the latest compiled JS script tag and CSS link tag from [cdnjs](https://cdnjs.com/libraries/mdb-ui-kit) to the application.

Don't forget to add also Font Awesome and Roboto font if you need. Here's an example code:

###### CSS

```css
<!-- Font Awesome -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
  rel="stylesheet"
/>
<!-- Google Fonts -->
<link
  href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap"
  rel="stylesheet"
/>
<!-- MDB -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.css"
  rel="stylesheet"
/>
```


###### JS

```javascript
<!-- MDB -->
<script
  type="text/javascript"
  src="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.js"
></script>
```

## Customization

##### Basic example

###### HTML
```html
<div class="accordion" id="accordionExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingOne">
      <button
        class="accordion-button"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-target="#collapseOne"
        aria-expanded="true"
        aria-controls="collapseOne"
      >
        Accordion Item #1
      </button>
    </h2>
    <div
      id="collapseOne"
      class="accordion-collapse collapse show"
      aria-labelledby="headingOne"
      data-mdb-parent="#accordionExample"
    >
      <div class="accordion-body">
        <strong>This is the first item's accordion body.</strong> It is hidden by default,
        until the collapse plugin adds the appropriate classes that we use to style each
        element. These classes control the overall appearance, as well as the showing and
        hiding via CSS transitions. You can modify any of this with custom CSS or
        overriding our default variables. It's also worth noting that just about any HTML
        can go within the <strong>.accordion-body</strong>, though the transition does
        limit overflow.
      </div>
    </div>
  </div>
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingTwo">
      <button
        class="accordion-button collapsed"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-target="#collapseTwo"
        aria-expanded="false"
        aria-controls="collapseTwo"
      >
        Accordion Item #2
      </button>
    </h2>
    <div
      id="collapseTwo"
      class="accordion-collapse collapse"
      aria-labelledby="headingTwo"
      data-mdb-parent="#accordionExample"
    >
      <div class="accordion-body">
        <strong>This is the second item's accordion body.</strong> It is hidden by
        default, until the collapse plugin adds the appropriate classes that we use to
        style each element. These classes control the overall appearance, as well as the
        showing and hiding via CSS transitions. You can modify any of this with custom CSS
        or overriding our default variables. It's also worth noting that just about any
        HTML can go within the <strong>.accordion-body</strong>, though the transition
        does limit overflow.
      </div>
    </div>
  </div>
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingThree">
      <button
        class="accordion-button collapsed"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-target="#collapseThree"
        aria-expanded="false"
        aria-controls="collapseThree"
      >
        Accordion Item #3
      </button>
    </h2>
    <div
      id="collapseThree"
      class="accordion-collapse collapse"
      aria-labelledby="headingThree"
      data-mdb-parent="#accordionExample"
    >
      <div class="accordion-body">
        <strong>This is the third item's accordion body.</strong> It is hidden by default,
        until the collapse plugin adds the appropriate classes that we use to style each
        element. These classes control the overall appearance, as well as the showing and
        hiding via CSS transitions. You can modify any of this with custom CSS or
        overriding our default variables. It's also worth noting that just about any HTML
        can go within the <strong>.accordion-body</strong>, though the transition does
        limit overflow.
      </div>
    </div>
  </div>
</div>
```

##### Flush

Add `.accordion-flush` to remove the default `background-color`, some borders, and some rounded corners to render accordions edge-to-edge with their parent container.

###### HTML

```html
<div class="accordion accordion-flush" id="accordionFlushExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="flush-headingOne">
      <button
        class="accordion-button collapsed"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-target="#flush-collapseOne"
        aria-expanded="false"
        aria-controls="flush-collapseOne"
      >
        Accordion Item #1
      </button>
    </h2>
    <div
      id="flush-collapseOne"
      class="accordion-collapse collapse"
      aria-labelledby="flush-headingOne"
      data-mdb-parent="#accordionFlushExample"
