twin.macro

Twin blends the magic of Tailwind with the flexibility of css-in-js (emotion, styled-components, solid-styled-components, stitches and goober) at build time. Maintained by ben-rogerson on GitHub, where it has earned 8,030 stars from the community.

It's actively developed around babel, babel-macro, css-in-js, and is a solid reference for anyone building with these tools.
