Implementation notes

About the Raw Block CSS button

Raw Block uses direct typography, strong borders and deliberately exposed structure. Its square geometry creates a compact, precise control. Its structure comes from a 4px border. The interaction stays intentionally restrained.

Usage

<button class="btn-raw-block">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: Square
Exports: CSS, Tailwind, React

We matched its palette, surface, geometry and motion to a complete UI system — like composing an outfit, not browsing unrelated parts.
