Implementation notes

About the Plasma Edge CSS button

Plasma Edge uses technical geometry and motion for an engineered visual language. Its rounded corners balance product-friendly softness with a clear boundary. It is built around a two-stop linear gradient anchored on #10131c, with a 5s keyframe animation and a 2px border. The animated, border fx details are included in the copy-paste CSS.

Usage

<button class="btn-plasma-edge">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.
