Tailwind Sunburst Expand Radiant Button Effect
A warm radiant CTA where a glow blooms from the centre on hover, flooding the button like a sunrise — an opaque flood, distinct from entry 28's fading ring. Design B swaps the bloom for repeating-conic-gradient rays that scale AND rotate into place.

Which parts became utilities, which stayed CSS, and why.
- Design B is the batch's last and clearest demonstration of the discrete-transform win:
translate(-50%,-50%) scale(1) rotate(30deg)— five values with the centring repeated in every state — becomes a permanent centring pair plusscale-100and[rotate:30deg]on hover. - The label's
text-shadowbloom is a one-utility addition with an outsized effect, and it is only obvious to add because the label's hover state is written next to the layer's. - UI change from the CSS original: both blooms fire on
group-focus-visible/btn:, design B's rays now fade in as well as grow (the original jumped to 0.6 opacity), and reduced motion keeps the rays present and unrotated at 40%.

```How this works
An opaque bloom, not a ripple. Entry 28 fades as it grows (energy dissipating); this one stays solid and floods (light arriving). Same two properties, opposite intent — and the pair is a good illustration that the technique is never the design decision.
The label participates. A text-shadow bloom on hover is what stops the effect looking like a background swap. It is one arbitrary utility and it does more for the illusion than the gradient's stops do.
Rays need scale and rotation together. Design B's conic layer arrives by growing from 0 and turning 30deg at the same time, which reads as light sweeping into place. In CSS that was transform: translate(-50%,-50%) scale(1) rotate(30deg) — five values, three of them repeated from the resting state. Here the hover names scale-100 and [rotate:30deg] and nothing else.
Make it yours
- Bloom reach:
hover:before:scale-[2.4]— enough to clear a pill; raise it for wide buttons. - Warmth:
--color-tbh34a-warm; the border, fill, bloom and ring all derive from it viacolor-mix(). - Ray density: the
6deg 18degstops — tighter angles read as a starburst, wider as a pinwheel. - Idle pulse: add
animate-pulse-style keyframes to the bloom layer for a button that breathes before it is touched.
Gotchas — read before shipping
overflow-hiddenclips the bloom; without it a 2.4× gradient disc paints across the page.- Keep the bloom below the label (
before:z-0vsrelative z-[1]), or the text washes out at full brightness. - Check label contrast at the BRIGHTEST frame — white text on a fully bloomed warm gradient is the risk, which is why design A keeps a solid ink and a text-shadow rather than lowering the text's opacity.
- Design B's rays are white at 50% over a light fill, so its label is dark ink; inverting either without the other fails contrast immediately.

Radial and repeating-conic gradients with transforms are universal; with CSS unavailable each button is a solid warm CTA.
