# nano-css

[![][npm-badge]][npm-url] [![][travis-badge]][travis-url]

__Tiny [5<sup>th</sup> generation](https://github.com/streamich/freestyler/blob/master/docs/en/generations.md#5th-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](https://bundlephobia.com/result?p=nano-css@1.15.3)__ in base configuration, *e.g. [`styled-components`](https://github.com/styled-components/styled-components) is [15.1Kb](https://bundlephobia.com/result?p=styled-components@3.2.5)*
- __Library-agnostic__ &mdash; use it standalone, with React, Preact, Vue.js, or any other library
- __Isomorphic__ &mdash; render on server and browser, generates stable class names, and re-hydrates
- __Performant__ &mdash; [*simply the fastest library*](https://github.com/streamich/CSS-IN-JS-Benchmarks/blob/master/RESULT.md); 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__ &mdash; [Unlicense license](./LICENSE)

> For pre-configured simple-to-use package see [`nano-theme`](https://github.com/streamich/nano-theme), which builds on top of `nano-css`.
