Html

<label>
	<input type="checkbox" />
	<span> Check Me Out! </span>
</label>
the <span> tag isn't needed but is nice to have once you start applying any grid or flex

CSS

label:has(input[type="checkbox"]) {
	cursor: pointer;
}

input[type="checkbox"] {
	appearance: none;
	position: relative;
	display: inline-block;
	background: lightgrey;
	height: 1.65rem;
	width: 2.75rem;
	vertical-align: middle;
	border-radius: 2rem;
	box-shadow: 0px 1px 3px #0003 inset;
	transition: 250ms linear background;
	cursor: pointer;
}

input[type="checkbox"]::before {
	content: "";
	display: block;
	width: 1.25rem;
	height: 1.25rem;
	background: #fff;
	border-radius: 1.2rem;
	position: absolute;
	top: 0.2rem;
	left: 0.2rem;
	box-shadow: 0px 1px 3px #0003 inset;
	transition: 0.25s linear transform;
	transform: translateX(0rem);
}
input[type="checkbox"]:checked {

input[type="checkbox"]:checked::before {
