Implementation notes

About the Letter Space CSS button

Letter Space uses restrained decoration that keeps the surrounding content in focus. Its rounded corners balance product-friendly softness with a clear boundary. The text fx details are included in the copy-paste CSS.

Usage

<button class="btn-letter-space">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.
