Neo-Brutalist Checkbox
A neo-brutalist checkbox: thick ink border, a hard offset shadow and flat color. Checking slams the box into its shadow and punches in a square-capped tick. The ink follows your text color.
Also known as: brutalist checkbox css, hard shadow checkbox, neubrutalism 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.
