What it is
UnoCSS is an atomic CSS engine that generates utility classes on demand, making it faster than Tailwind CSS for large projects by only generating exactly the CSS that is used. It is fully compatible with Tailwind CSS classes and supports custom rules, presets, and icons. UnoCSS is popular in the Vue and Nuxt ecosystem and for performance-sensitive projects.
