Material Design Checkbox with Ripple
The Material pattern in plain CSS: a soft halo on hover, a ripple that spreads and fades when you check it, and a tick that draws across the filled box. Box and halo follow Material's proportions.
Also known as: material checkbox css, ripple checkbox, material ui checkbox.

}Customizing this snippet
- Color: set
--chk-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--chk-size. Every other dimension is inem, so the whole thing scales together. Currently previewing24px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
