Implementation notes

About the Starlight CSS button

Starlight uses luminous contrast designed for dark and futuristic interfaces. Its rounded corners balance product-friendly softness with a clear boundary. The particles details are included in the copy-paste CSS.

Usage

<button class="btn-starlight">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: Rounded
Exports: CSS, Tailwind, React
