# UnoCSS

Unclassified · [Official website](https://uno.antfu.me/)

UnoCSS is an open source atomic CSS engine created by Anthony Fu. It generates only the utility CSS classes a project actually uses, at build time, and can be configured with presets compatible with frameworks such as Tailwind CSS. As a styling tool it does not track visitors and does not require consent.
