Implementation notes

About the Rainbow Pop CSS button

Rainbow Pop uses expressive color, shape and feedback for characterful products. Its rounded corners balance product-friendly softness with a clear boundary. It combines a three-layer shadow, a 2px border and a 200ms hover shift. The hover reveal details are included in the copy-paste CSS.

Usage

<button class="btn-rainbow-pop">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
