Open Props

open-props.style

Sub-atomic styles: an open source set of expertly crafted CSS custom properties for consistent, adaptive design, installable from a CDN or NPM.

What is Open Props?

Open Props ships web design tokens as plain CSS custom properties — colors, sizes, shadows, radii, easings, animations and named media queries. Import everything from unpkg or NPM and drop the variables into any framework, since they are just CSS. It is MIT licensed and aimed at making adaptive, consistent components faster to build.
