Implementation notes

About the Liquid Glass Sheen CSS button

Liquid Glass Sheen uses a translucent surface designed to work over rich backgrounds. Its pill silhouette makes the label easy to scan in compact layouts. A two-layer shadow gives it its depth, with motion handled by a 5s keyframe animation. The liquid, animated, border fx details are included in the copy-paste CSS.

Usage

<button class="btn-liquid-glass-sheen">Button</button>

Pair it with the CSS tab above — the class is self-contained.

Before shipping: keep the semantic button element, verify contrast on your actual background and add a visible:focus-visible state. If you retain motion, include a prefers-reduced-motion override.

Built with: HTML + plain CSS
Shape: Pill
