Reference

Generated and hand-written reference material — the complete utility index, every CSS custom property, and fluidity's documented limitations.

The utility index and CSS variables pages are generated directly from index.css by scripts/build-docs-reference.mjs, so they can’t drift from what fluidity actually ships. Limitations is hand-written from the same constraints documented in the README.

Utility index

Every one of the 279 generated utility classes, grouped by property and curve.

CSS variables

The 5 custom properties and 15 setter utilities that configure every ramp.

Limitations

What fluidity deliberately doesn’t validate or support, and the browser baseline.
