To-Do Task Card Checkbox
A task card that completes in one gesture: a tint sweeps across the row, the round check squashes and bounces, the text slides aside and a Done pill pops in. Every piece reverses on uncheck.
Also known as: todo item complete animation, task list checkbox css, complete task animation.

}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.
