Bouncy Pop Checkbox

A satisfying, tactile toggle: on check the mark overshoots its size with a spring cubic-bezier before settling, and the box gives a tiny squash. That physical bounce is what makes a checkbox feel alive — done entirely with transform.

## JavaScript
```js
/* No JavaScript — an overshoot cubic-bezier + squash keyframe give the bounce. */
```

How this works

The state comes from :checked as usual, but the delight is in the timing function. The check glyph scales from 0 to slightly over 1 and back using a cubic-bezier with an overshoot (values >1), so it pops past its final size and springs back — the classic elastic feel.

The box itself runs a brief squash-and-stretch keyframe (scale on X/Y) on check for extra physicality. All motion is transform-only, so it composites on the GPU and never reflows. Standard sr-only input keeps it accessible with a :focus-visible ring.

Under prefers-reduced-motion the spring is replaced with a plain fade so motion-sensitive users still get clear feedback.

Make it yours

  • Dial the bounce with the check's cubic-bezier — raise the third/fourth values for more overshoot.
  • Adjust squash intensity in the cb-10-pop keyframes.
  • Recolour via --accent.
  • Slow or speed the pop with the transition duration.

Gotchas — read before shipping

  • Only transform should carry the bounce — never animate width/height, which would reflow.
  • Overshoot beziers can look broken if the duration is too long; keep it ~180–260ms.
  • Respect reduced-motion — springy overshoot is exactly the kind of motion that affects some users.
