:checked
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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
label, input[type="submit"] { display: block; margin-top: 1em; } input:checked { border: none; outline: 2px solid deeppink; } <form> <p>How did you find out about us?</p> <label ><input name="origin" type="radio" value="google" checked /> Google</label > <label><input name="origin" type="radio" value="facebook" /> Facebook</label> <p>Please agree to our terms:</p> <label ><input name="newsletter" type="checkbox" checked /> I want to subscribe to a personalized newsletter.</label > <label ><input name="privacy" type="checkbox" /> I have read and I agree to the Privacy Policy.</label > <input type="submit" value="Submit form" /> </form> 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. Customizable select element functionality can be used to enable full customization of <option> elements just like any regular DOM element, in supporting browsers.

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
<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: #dddddd; } /* Style the button */ #expand-btn { display: inline-block; margin-top: 12px; padding: 5px 11px; background-color: #ffff77; 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: #cccccc; } Result
