: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 (), checkbox (), or option ( in a 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;
}
The user can engage this state by checking/selecting an element, or disengage it by unchecking/deselecting the element.
Note:
Because browsers often treat 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 elements just like any regular DOM element, in supporting browsers.
Syntax
:checked {
/* ... */
}
