Tailwind Shimmer Shine Button Hover Effect

Five reflective button surfaces — diagonal gloss, radial spotlight, frosted double edge, holographic foil and a full shimmer wash. Each is a gradient on a pseudo-element swept across the face and clipped by overflow-hidden.

What changed in the port

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

  • Five effects, zero new CSS rules beyond one keyframe: every sweep is a gradient plus a transform, both of which have utility forms.
  • UI change from the CSS original: the shimmer now fires on focus-visible:, so keyboard users get the same affordance feedback, and every button holds a 44px target.
  • The wash uses forwards rather than a transition so a fast mouse-out cannot strand the streak mid-button.

How this works

One gradient, one transform. The gloss is before:[background:linear-gradient(105deg,transparent_0%,rgba(255,255,255,.7)_50%,transparent_100%)] sitting at before:-left-[75%]; hover moves it to before:left-[125%], and the button's overflow-hidden does the clipping.

The frosted variant needs both pseudo-elements. before: slides in from the left edge and after: mirrors it from the right, each with its own translate-x — the two-edge shimmer the CSS version built with the same pair.

The wash is a one-shot animation. A left transition would reverse on mouse-out mid-sweep; animate-thv09-wash with forwards plays the full pass and settles.

Make it yours

  • Streak width: change the gradient's 40% / 50% / 60% stops to 20% / 50% / 80% for a broad soft sweep.
  • Tint it gold with rgba(255,215,0,.5) in the middle stop.
  • Angle: 105deg → 45deg for corner-to-corner, 90deg for a flat wipe.

Gotchas — read before shipping

  • If the streak does not clear the button, widen it or push the end position past 125%.
  • On touch, :hover fires on tap but the finger may lift before the sweep completes — shorten the duration for mobile-first surfaces.
  • Keep any hover:shadow-* glow modest; a strong halo competes with the streak.
