Which parts became utilities, which stayed CSS, and why.
backdrop-blur-*andbackdrop-saturate-*compose into onebackdrop-filtercorrectly, which is the single strongest argument for utilities on this demo — hand-written CSS routinely declares the property twice and silently drops the first.- The
-webkit-backdrop-filterprefixes and the@supports notfallback both stay in CSS. Tailwind emits the unprefixed property only, and a feature query has no variant form (nor should it). - Alpha is expressed with Tailwind's slash syntax throughout (
bg-white/10,checked:bg-ttg21-tint/25) rather than as pre-mixed rgba tokens, so one tint colour serves the fill, the border and the glow at three different opacities. - UI change from the CSS original: supporting text went from
rgba(255,255,255,.65)towhite/75and the checked state now also brightens the border — previously the only on-signal was a 22% green wash, which is roughly a 1.2:1 change and effectively invisible to anyone with reduced colour vision.

```How this works
Glass needs three layers or it is just a grey box. Something colourful behind (two blurred gradient blobs), a translucent pane that blurs what is behind it, and light edges — a hairline white border plus an inset top highlight that implies thickness. Remove any one and the effect collapses.
The thumb is denser glass, not white. Higher alpha and its own blur make it read as a puck resting ON the pane rather than a hole punched through it.
The tint must stay gentle. Checked, the track goes to roughly 20% green. Push it past 30% and the material reads as painted plastic — which is why the state also carries a brighter border, so the signal survives without the fill getting heavier.
Make it yours
- Recolour the scene through the two blob tokens; the glass adapts on its own.
- Milkier pane:
backdrop-blur-[20px]andbg-white/25. - Add a specular sweep: a rotated white stripe at 6% alpha across the track.
- State tints: amber for pending, green for on, red for blocked — all at the same low alpha.
Gotchas — read before shipping
backdrop-filtersamples what is BEHIND the element. A solid background on the parent kills the effect entirely — this is the number-one reason glass demos look flat when pasted into a real page.- Ship the
@supports notfallback. Firefox before 103 and several Android WebViews render the pane fully transparent without it, which makes the label unreadable rather than merely unstyled. - Translucency erodes contrast. Keep label text fully opaque white and the focus ring solid — never
white/70on a pane whose backdrop you do not control. - Two 340px blurred blobs on an infinite loop are the most expensive thing in this collection; they are paused under
motion-reduce:and should be dropped entirely on low-end targets.
Browser support
| Chrome | Safari | Firefox | Edge |
|---|---|---|---|
| 111+ | 16.4+ | 128+ | 111+ |
backdrop-filter is broadly supported (Firefox 103+); the demo ships an @supports not fallback with a solid pane so the control stays readable without it.
