How this works

The canonical pattern in its cleanest form: sr-only checkbox → 51×31 track span → 27px thumb span. The track uses Apple's translucent off-gray rgba(120,120,128,0.32) so it sits naturally on dark surfaces, snapping to #34c759 when checked; the thumb slides 20px on transform:translateX with the Material-standard (0.4, 0, 0.2, 1) curve.

The thumb shadow is deliberately tighter than real iOS — on a card-based gallery a soft cast shadow would bleed outside the track, so a 1–2px contact shadow keeps it contained. Focus is a 2px iOS-blue outline offset from the track, drawn via input:focus-visible ~ .track.

Make it yours

System blue focus ring and green on-state are both single hex swaps.
Scale proportionally: keep travel = width − thumb − 2×inset (20px here).
Loosen the shadow back to iOS-authentic if your surface is a full screen, not a card.
Add the :active thumb stretch from demo 01 for the native squash.

Gotchas — read before shipping

Translucent track grays only read correctly on the surface they were tuned for — retune the rgba on light backgrounds (or use demo 44).
Slide with transform, not left — this exact demo is the INP benchmark case.
Never display:none the input; the sr-only clip pattern keeps it in the tab order.

Transforms + sibling :checked; effectively universal.
