## JavaScript
```js
/* Wire the range input to the CSS custom property so the slider drives
   the clip-path reveal. Pure CSS would be possible via :has() but value-
   reading from CSS isn't supported widely yet; this 5-line script is the
   reliable cross-browser path. */
(function () {
  var slider = document.getElementById('ss-bef-r');
  var stage  = slider && slider.closest('.ss-bef').querySelector('.ss-bef-stage');
  if (!slider || !stage) return;
  function sync() { stage.style.setProperty('--ss-bef-pct', slider.value); }
  slider.addEventListener('input', sync);
  sync();
})();
```

How this works

Two panels stack in the same grid cell using grid-area: 1 / 1. The top panel gets clip-path: inset(0 calc(100% - var(--pos)) 0 0) so it's revealed only up to the --pos value. An <input type='range'> spans the wrapper with position: absolute; inset: 0 and opacity: 0, catching drag events across the whole surface. Under 20 lines of JS listen for input and write style.setProperty('--pos', value + '%') on the wrapper. A vertical handle uses left: var(--pos) and pointer-events pass through to the range. The handle itself uses translate: -50% 0 to center on the seam.

Make it yours

  • Change the starting split by editing the range's value attribute and the wrapper's inline --pos. Keep them in sync or the handle jumps on first drag.
  • Swap to a horizontal slider revealing top/bottom by changing clip-path to inset(0 0 calc(100% - var(--pos)) 0) and moving the handle to top: var(--pos); left: 0; right: 0 with a horizontal grip.
  • Style the handle by editing its width, background, and the arrow pseudo-elements. A 2px line with a 44px circular grip reads more premium than a full-height bar.
  • Add snap points by setting step on the range input. step='25' gives quarter-position snapping useful for demo comparisons.

Gotchas — read before shipping

  • Range inputs default to arrow-key stepping of 1%. Keyboard users hit the handle 100 times to cross the panel — set step='5' and add aria-label describing what's being compared.
  • clip-path transitions aren't animated by default on cheap Android GPUs and can jank. Skip transitioning it; only the handle's left needs to feel smooth via transition: none on the clip and will-change: left on the handle.
  • Touch drags fire input at high frequency. Throttle with requestAnimationFrame if you're doing anything heavier than a custom property write, or the main thread stalls on low-end devices.
