Implementation notes
About the Slate Calm CSS button
Slate Calm uses a clear, high-contrast treatment for primary product actions. Its rounded corners balance product-friendly softness with a clear boundary. The interaction stays intentionally restrained.
Usage
<button class="btn-slate-calm">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
