## What it is
cxs is a minimal 0.7kb CSS-in-JS library that uses an atomic CSS approach for high performance and style deduplication. It is framework-independent with an optional React higher-order component API and supports server-side rendering via a static CSS string extraction method.

## Use cases
- generate css styles from javascript objects
- style react components without css files
- deduplicate repeated css rules for performance
- extract static css for server-side rendering
- add pseudoclasses and media queries in js
- create styled components with a tiny footprint

## When to choose
- you need an extremely small css-in-js solution with zero dependencies
- you want atomic css deduplication and dead-code elimination
- you need framework-independent styling with optional react support
- you want server-side rendered static css strings

## When to avoid
- you need client-side style rehydration for universal apps
- you want a full-featured styling solution with theming and advanced features
- you prefer tagged template literal css syntax
- you need an actively developed library with recent updates
