Implementation notes

About the Accent Bar CSS button

Accent Bar uses a lightweight treatment that keeps secondary actions visible. Its asymmetric geometry creates a deliberate visual focal point. The interaction stays intentionally restrained.

Usage

<button class="btn-accent-bar">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: Asymmetric
Exports: CSS, Tailwind, React
