Implementation notes

About the Chrono Ring CSS button

Chrono Ring uses technical geometry and motion for an engineered visual language. Its circular geometry works best for a short label or icon-led action. Motion comes from an 8s keyframe animation. The animated, border fx details are included in the copy-paste CSS.

Usage

<button class="btn-chrono-ring">GO</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
