CSS Checkmark Checkbox Without SVG
Two pseudo-element strokes draw the tick in order, short leg then long leg, the way a pen would. Unchecking lifts them in reverse. Pure CSS transforms, no SVG and no images.
Also known as: css only checkmark animation, tick mark css, checkmark without svg.

}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.
