:checked
========

The **`:checked`** CSS pseudo-class selector represents any **radio** (`<input type="radio">`), **checkbox** (`<input type="checkbox">`), or **option** (`<option>` in a `<select>`) element that is checked or toggled to an `on` state.

Try it
------

The user can engage this state by checking/selecting an element, or disengage it by unchecking/deselecting the element.

**Note:** Because browsers often treat `<option>`s as replaced elements, the extent to which they can be styled with the `:checked` pseudo-class varies from browser to browser.

Syntax
------


```css
:checked {
  /\* ... \*/
}
```

Examples
--------

### Basic example

#### HTML


```html
<div>
  <input type="radio" name="my-input" id="yes" value="yes" />
  <label for="yes">Yes</label>

  <input type="radio" name="my-input" id="no" value="no" />
  <label for="no">No</label>
</div>

<div>
  <input type="checkbox" name="my-checkbox" id="opt-in" />
  <label for="opt-in">Check me!</label>
</div>

<select name="my-select" id="fruit">
  <option value="opt1">Apples</option>
  <option value="opt2">Grapes</option>
  <option value="opt3">Pears</option>
</select>
```


#### CSS


```css
div,
select {
  margin: 8px;
}

/\* Labels for checked inputs \*/
input:checked + label {
  color: red;
}

/\* Radio element, when checked \*/
input[type="radio"]:checked {
  box-shadow: 0 0 0 3px orange;
}

/\* Checkbox element, when checked \*/
input[type="checkbox"]:checked {
  box-shadow: 0 0 0 3px hotpink;
}

/\* Option elements, when selected \*/
option:checked {
  box-shadow: 0 0 0 3px lime;
  color: red;
}
```

### Toggling elements with a hidden checkbox

This example utilizes the `:checked` pseudo-class to let the user toggle content based on the state of a checkbox, all without using JavaScript.

#### HTML


```html
<input type="checkbox" id="expand-toggle" />

<table>
  <thead>
    <tr>
      <th>Column #1</th>
      <th>Column #2</th>
      <th>Column #3</th>
    </tr>
  </thead>
  <tbody>
    <tr class="expandable">
      <td>[more text]</td>
      <td>[more text]</td>
      <td>[more text]</td>
    </tr>
    <tr>
      <td>[cell text]</td>
      <td>[cell text]</td>
      <td>[cell text]</td>
    </tr>
    <tr>
      <td>[cell text]</td>
      <td>[cell text]</td>
      <td>[cell text]</td>
    </tr>
    <tr class="expandable">
      <td>[more text]</td>
      <td>[more text]</td>
      <td>[more text]</td>
    </tr>
    <tr class="expandable">
      <td>[more text]</td>
      <td>[more text]</td>
      <td>[more text]</td>
    </tr>
  </tbody>
</table>

<label for="expand-toggle" id="expand-btn">Toggle hidden rows</label>
```


#### CSS


```css
/\* Hide the toggle checkbox \*/
#expand-toggle {
  display: none;
}

/\* Hide expandable content by default \*/
.expandable {
  visibility: collapse;
  background: #ddd;
}

/\* Style the button \*/
#expand-btn {
  display: inline-block;
  margin-top: 12px;
  padding: 5px 11px;
  background-color: #ff7;
  border: 1px solid;
  border-radius: 3px;
}

/\* Show hidden content when the checkbox is checked \*/
#expand-toggle:checked ~ \* .expandable {
  visibility: visible;
}

/\* Style the button when the checkbox is checked \*/
#expand-toggle:checked ~ #expand-btn {
  background-color: #ccc;
}
```
