Tiny 5^th generation CSS-in-JS library that you can actually use in production. Motto of nano-css is simple: create the smallest possible CSS-in-JS library and provide all features of any other library through addons.

• Only 0.5 Kb in base configuration, e.g. styled-components is 15.1Kb
• Library-agnostic — use it standalone, with React, Preact, Vue.js, or any other library
• Isomorphic — render on server and browser, generates stable class names, and re-hydrates
• Performant — simply the fastest library; does not create wrapper components, does not use inline styles or inline <style> elements, but caches all styles for re-use and injects CSS using .insertRule() for performance
• @media queries and animation @keyframes are supported
• Auto-prefixes your styles
• Extract CSS into external style sheet
• Public domain — Unlicense license

For pre-configured simple-to-use package see nano-theme, which builds on top of nano-css.
