Getting Started

What's the fastest way to try the framework?

Link https://cdn.cssvars.com/cssvars.css in your HTML <head> and start adding classes — there's nothing to install or build.

Do I need Node.js or npm?

No. The framework is distributed as a single CSS file, so no package manager or build tooling is required to use it.

Theming

Can I rebrand the whole site by editing a few variables?

Yes — override --color-1, --color-2, and the other root tokens in your own stylesheet loaded after cssvars.css.

Components

How do checkbox/radio toggle components work?

A hidden checkbox or radio input drives the :checked state, and sibling selectors reveal or style the connected content — the same pattern powering this accordion.

Licensing & Support

Is the framework free for commercial projects?

Yes, it's open source and free to use — check the license in the GitHub repository for full details.
