Home / CSS – Tutorial / CSS checkbox style

The checkbox is an HTML attribute used to take input from the user.

1. we are using the ‘~'(sibling combinator). It selects over all elements that are preceded by the previous selector.

Example:

<!DOCTYPE html>
<html>
<style>
.container {
 display: block;
 position: relative;
 padding-left: 35px;
 margin-bottom: 20px;
 cursor: pointer;
 font-size: 25px;
}

/* Hide the default checkbox */
.container input {
 visibility: hidden;
 cursor: pointer;
}

/* Create a custom checkbox */
.mark {
 position: absolute;
 top: 0;
 left: 0;
 height: 25px;
 width: 25px;
 background-color: lightgray;
}

.container:hover input ~ .mark {
 background-color: gray;
}

.container input:checked ~ .mark {
 background-color: blue;
}

/* Create the mark/indicator (hidden when not checked) */
.mark:after {
 content: "";
 position: absolute;
 display: none;
}

/* Show the mark when checked */
.container input:checked ~ .mark:after {
 display: block;
}

/* Style the mark/indicator */

 left: 9px;

 width: 5px;
