Shine Border

A subtle animated shimmer that sweeps around the border of its container. Where border beam is a discrete travelling light, the shine is an ambient glow on the border ring - a hint of life for cards, inputs and CTAs that shouldn't demand attention. Pure CSS, zero JavaScript, and it holds still under prefers-reduced-motion.
Basic Shine Border

Wrap any content. The component renders a panel (surface, hairline border, theme radius) and sweeps the shimmer around its ring. With no border_radius set it follows the theme radius token.

Colour Blends

shine_color takes a single CSS colour or a list - a list blends across the sweep. Slow the lap down with duration and thicken the ring with border_width when the shine is the point.

Now shipping: 4.4.0

One design system, nineteen components, zero JavaScript.

On Dark Panels

The shimmer reads best where the border is the brightest thing on screen. On a near-black panel a slow gold shine makes a quiet premium badge.
