Windi CSS
ELI5 — The Vibe Check
Windi CSS was the framework that proved on-demand CSS generation was the future — so much so that Tailwind adopted the idea as JIT mode. It pioneered scanning your code and generating only the classes you actually use. The trailblazer that inspired the revolution.
Real Talk
Windi CSS was an on-demand utility CSS framework that introduced the concept of scanning source files and generating only used utility classes. It inspired Tailwind's JIT mode and offered features like attributify mode and variant groups. Development has been succeeded by UnoCSS.
