## JavaScript
```js
/* No JavaScript — radios drive a grid-template-rows 0fr→1fr reveal, and :has() lifts the open card clear of the stack. */
```

How this works

Each panel pairs a hidden <input type="radio"> (shared name) with a <label> header and a body wrapped in a grid-template-rows:0fr container. Checking a radio animates that wrapper to 1fr, so the body reveals by animating grid rows — the modern, jump-free way to expand from height auto. Sibling cards simply reflow down in the normal document flow.

Resting cards overlap slightly via negative margins for the 'stacked' look; the open card lifts clear with a shadow. Radios keep native keyboard arrow-navigation and a focus ring.

Make it yours

  • Switch name to checkboxes to allow multiple open at once.
  • Change the resting overlap with the negative margin-top.
  • Retime the reveal via the grid-rows transition duration.
  • Recolour the active card border through --accent.

Gotchas — read before shipping

  • Animate grid-template-rows 0fr→1fr, not height:auto, which can't transition.
  • Keep radios sr-only but focusable so keyboard + screen readers work.
  • Give the body overflow:hidden so clipped content doesn't leak while collapsed.

Floor set by :has(), oklch() as this demo is written. The core technique itself goes back further — Chrome 107+.

Animating grid-template-rows to 0fr/1fr is supported in current Chrome, Safari and Firefox; older engines snap open without the tween.
