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.
/* Matches any checked/selected radio, checkbox, or option */
:checked {
margin-left: 25px;
border: 1px solid blue;
}
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.

Result
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
<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
/* 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;
}
Result
Image gallery
You can use the :checked
pseudo-class to build an image gallery with full-size images that show only when the user clicks on a thumbnail. See this demo for a possible cue.
Note: For an analogous effect, but based on the :hover
pseudo-class and without hidden radioboxes, see this demo, taken from the :hover reference page.
