How this works

backdrop-filter: blur() saturate() over a translucent fill frosts the backdrop, and an inset hairline reads as glass thickness. A ::after diagonal gradient parked off-edge transitions across on hover for the shimmer.

The sweep composites cleanly, and :focus-visible shows a bright ring over busy backdrops.

Make it yours

  • Push blur/saturate for realism (cap ~24px for INP).
  • Change the shimmer angle and skew.
  • Tint via --tint with color-mix().
  • Slow the sweep by lengthening the transition.

Gotchas — read before shipping

  • backdrop-filter needs a non-opaque layer behind it — place over an image/gradient.
  • Add -webkit-backdrop-filter and isolation:isolate.
  • Keep the label on a solid-enough tint for WCAG contrast.

Floor set by oklch(), color-mix(), backdrop-filter as this demo is written. The core technique itself goes back further — Chrome 76+.

backdrop-filter is progressive — without it the button is a semi-solid frosted capsule that still shimmers.
