## What it is
ReactCSS is a JavaScript library for defining inline styles in React and React Native using a class-based style object. It supports autoprefixing, hover states, pseudo-elements, and media queries through activated style classes.

## Use cases
- style react components with inline styles
- apply conditional style classes in react
- autoprefix inline styles in javascript
- handle hover and pseudo-elements with inline styles
- share styles between react and react native
- define media queries in inline styles

## When to choose
- you prefer inline styles over css files in react
- you need class-like conditional styling with inline styles
- you want one styling approach for react and react native

## When to avoid
- you use modern css-in-js solutions like styled-components or emotion
- you need a actively maintained library with recent updates
- your project relies on css modules or plain stylesheets

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, css-framework
- domain: frontend, web-development
- platform: cross-platform
- tags: inline-styles, react, react-native, css-in-js, styling, nodejs
