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.




Basic example


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

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

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

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


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.


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

    <tr><th>Column #1</th><th>Column #2</th><th>Column #3</th></tr>
    <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>

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


/* 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;
