Bouncy Checkbox Animation in Tailwind CSS — Spring cubic-bezier
A squash-and-stretch pop on check: peer-checked:animate-tcb10-pop squeezes the box to 82% then overshoots to 112%, while the tick springs in on an ease-[cubic-bezier(.34,1.7,.5,1)] overshoot curve. Pressing now squashes the box before release.

Which parts became utilities, which stayed CSS, and why.
@keyframes cb-10-pop{transform:scale(…)}became a token animation over the standalonescaleproperty — v4's native transform model.- The tick's
::aftermask became an inline SVG withscale-0 → group-has-checked:scale-100. - UI upgrade from the CSS original: press anticipation (
group-active:scale-90) so the bounce reads as a release, and rows are 52px tall. - UI upgrade: the empty-box border rose from
#e3b7ad(1.8:1) to 3:1 on white.

```How this works
Keyframes vs. transition. The box uses a keyframe (it must dip and overshoot); the tick uses a transition with an overshooting bezier (one move, springy landing).
v4 scale is its own property. Tailwind v4 compiles scale-* to the standalone scale property, so the keyframes animate scale directly and never fight translate utilities.
Anticipation. group-active:scale-90 squashes while the pointer is down, so the pop reads as a release.
Make it yours
- Heavier bounce: raise the bezier's second value to 2.
- Heart variant: swap the tick path for a heart and
--color-tcb10-accfor pink. - Only on check: the pop runs on
:checked; add ananimate-tcb10-popto the unchecked state for a double-bounce. - Duration: edit the
--animate-tcb10-poptoken.
Gotchas — read before shipping
- An animation runs when its rule starts matching — initially-checked boxes pop on page load.
- Cubic-bezier y-values above 1 overshoot; x-values must stay within 0–1.
- Keep the pop ≤350ms: longer bounces make repeated toggling feel sluggish.
