No. The framework ships as a single stylesheet, cssvars.css. Link it from the CDN and start writing HTML — there's no npm install, no config file, and no compile step required.

Every color, spacing, and typography value is exposed as a CSS custom property in :root. Override --color-1, --color-2, and the rest directly in your own stylesheet — no JavaScript theme switcher needed.

Zero JavaScript. Interactive components like this accordion, toggles, tabs, and menus are built with the CSS checkbox and radio toggle pattern, so everything works with pure CSS.

It's built for static and server-rendered sites, marketing pages, and small teams who want fast iteration without a build pipeline. If your project already relies on a heavy component library, a bundler-based framework like Bootstrap or Tailwind may fit better.

Link it directly from https://cdn.cssvars.com/cssvars.css, or clone the source from the GitHub repository if you'd like to customize the framework itself.
