Tailwind Sliding Pill Radio Switch

A three-way pill where the thumb glides between options and changes colour as it lands — Pickup amber, Delivery green, Dine-in violet. Position and hue come from one custom property per state: has-[label:nth-child(2)_input:checked]:[--thumb:…] on the track, read by before:bg-(--thumb).

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • The four :has(nth-child) rules became four arbitrary variants on the track — two write translate, two write --thumb.
  • background:var(--thumb) became v4's parenthesis shorthand before:bg-(--thumb).
  • UI upgrade from the CSS original: Pickup now inks dark on the amber thumb — white on amber was 2.1:1, now 11:1 — and the green/violet stops were deepened so white text clears 4.5:1.
  • UI upgrade: a live caption answers what each mode means (ready time, fee, table hold), switched by group-has-[[value=…]:checked]/how:, and segments hold 48px.

How this works

State writes a variable, paint reads it. The track holds two arbitrary-variant classes per position — one for translate, one for --thumb. The thumb pseudo-element never changes class; it just reads --thumb.

Contrast per stop. White text passes on green and violet but fails on amber (2.1:1), so the first segment inks dark when checked. One variant, per label, where the colour is known.

Make it yours

  • Per-stop colours: edit the three --color-trb08-* tokens.
  • Four stops: thumb w-[calc(25%-2.5px)] plus a fourth translate/colour pair.
  • Caption copy lives in three spans below the track.

Gotchas — read before shipping

  • All translate rules must share the same transition, or the thumb teleports between states.
  • Test label contrast against every thumb colour, not just the default.
  • translate-x-full is relative to the thumb's own width, so its width must equal one segment exactly.

Without :has() options still select; the pill loses its slide.
