This pure CSS code snippet helps you to style custom checkbox. It comes with modern styles on modern browsers and classical checkboxes for IE8 and lower. The code hides the original checkbox and creates custom checkbox styles for improved accessibility and design. It’s a helpful solution for elevating your checkbox design.

Plus, it maintains compatibility with older browsers like IE8 for a seamless design across all platforms. You can use this code on your website to style checkboxes for more modern look.

How to Create Pure CSS Custom Checkbox Style

1. Begin by creating your HTML structure. Add checkboxes within <input> elements and their corresponding labels with <label> elements. Each checkbox should have a unique id attribute, and the for attribute of the label should match the checkbox’s id.

<h1>Accessible Custom checkboxes with CSS only</h1>
<h2>"automatic" fallback for IE</h2>

<form action="#">
    <input type="checkbox" id="test1" />
    <label for="test1">Red</label>
    <input type="checkbox" id="test2" checked="checked" />
    <label for="test2">Yellow</label>
    <input type="checkbox" id="test3" checked="checked" disabled="disabled" />
    <label for="test3">Green</label>
      <input type="checkbox" id="test4" disabled="disabled" />
      <label for="test4">Brown</label>

2. Copy and paste the following CSS code into your project. This CSS code defines the styles for both checked and unchecked checkboxes and handles various states like disabled and focused checkboxes.

/* Base for label styling */
	[type="checkbox"]:checked {
		position: absolute;
		left: 0;
		opacity: 0.01;
	[type="checkbox"]:not(:checked) + label,
	[type="checkbox"]:checked + label {
		position: relative;
		padding-left: 2.3em;
		font-size: 1.05em;
		line-height: 1.7;
		cursor: pointer;

	/* checkbox aspect */
	[type="checkbox"]:not(:checked) + label:before,
	[type="checkbox"]:checked + label:before {
		content: '';
		position: absolute;
		left: 0;
		top: 0;
		width: 1.4em;
		height: 1.4em;
		border: 1px solid #aaa;
		background: #FFF;
		border-radius: .2em;
		box-shadow: inset 0 1px 3px rgba(0,0,0, .1), 0 0 0 rgba(203, 34, 237, .2);
		-webkit-transition: all .275s;
				transition: all .275s;

	/* checked mark aspect */
	[type="checkbox"]:not(:checked) + label:after,
	[type="checkbox"]:checked + label:after {
		content: '✕';
		position: absolute;
		top: .525em;
		left: .18em;
		font-size: 1.375em;
		color: #CB22ED;
		line-height: 0;
		-webkit-transition: all .2s;
				transition: all .2s;

	/* checked mark aspect changes */
	[type="checkbox"]:not(:checked) + label:after {
		opacity: 0;
		-webkit-transform: scale(0) rotate(45deg);
				transform: scale(0) rotate(45deg);

	[type="checkbox"]:checked + label:after {
		opacity: 1;
		-webkit-transform: scale(1) rotate(0);
				transform: scale(1) rotate(0);

	/* Disabled checkbox */
	[type="checkbox"]:disabled:not(:checked) + label:before,
	[type="checkbox"]:disabled:checked + label:before {
		box-shadow: none;
		border-color: #bbb;
		background-color: #e9e9e9;

	[type="checkbox"]:disabled:checked + label:after {
		color: #777;

	[type="checkbox"]:disabled + label {
		color: #aaa;

	/* Accessibility */
	[type="checkbox"]:checked:focus + label:before,
	[type="checkbox"]:not(:checked):focus + label:before {
		box-shadow: inset 0 1px 3px rgba(0,0,0, .1), 0 0 0 6px rgba(203, 34, 237, .2);
