A React component library that recreates Chromium's native cr_elements design system — the one Chromium uses for chrome://settings, the bookmarks manager, the side panel, and other first-party WebUI surfaces.
Drop it into your extension, companion app, or internal tool and it will look like it ships with the browser. Dark mode is automatic; there is no CSS-in-JS runtime.
Tokens, spacing, typography, elevation, and focus rings mirror cr_shared_vars.css — the real thing, not a Material approximation.
Plain CSS with custom properties. 19 kB JS + 7 kB CSS gzip. No styled-components, no emotion, no theming engine.
Switches on prefers-color-scheme; force it with data-cr-theme="dark". No provider, no context.
Designed first for browser extension popups and side panels. Works equally well in Next.js, Electron, Tauri.
