Skeuomorphic Rotary Knob Toggle

A machined aluminum knob that rotates between OFF and ON detents: brushed-metal conic sheen, a milled indicator line, tick marks on the bezel, and a pilot LED that ignites at the ON detent. The checkbox IS the knob — click or Space twists it.

## JavaScript
```js
/* No JavaScript — the round checkbox rotates -32°→32° with a detent bezier; conic-gradient machining turns with it while ticks, legends and the LED stay fixed. */
```

How this works

The knob is a round appearance:none checkbox. Brushed metal is a conic-gradient of alternating light/dark stops under a radial highlight; the indicator is a ::before bar near the rim. State rotates the WHOLE input rotate(-32deg → 32deg) with a springy bezier, so the machined texture turns with the pointer — the detail that sells the machining.

OFF/ON legends and tick marks sit on a static bezel wrapper (they must not rotate). The LED is a sibling span lit by :checked ~ with a two-layer glow. :active scales the knob down 3% — the finger-grip press.

Make it yours

  • Widen the throw (±45deg) for a heavier industrial feel.
  • Recolor the LED via --led.
  • Add more detents visually with extra tick marks (they're just positioned spans).
  • Swap the aluminum for black anodize: darken the conic stops, keep the highlight.

Gotchas — read before shipping

  • Rotate the input itself, not just the indicator — a static texture under a moving line looks like a sticker.
  • Legends and ticks live OUTSIDE the rotating element or they'd turn too.
  • Round controls need generous hit area — keep the full 88px disc clickable, not just the indicator.

Floor set by :has(), oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 69+.

conic-gradient + transforms; supported in all evergreen browsers. Degrades to a flat disc with a working indicator if conic is unavailable.
