## What it is
Radium is a set of tools for managing inline styles on React elements, supporting hover/focus/active states, media queries, vendor prefixing, and keyframe animations without CSS files. It is an early CSS-in-JS library that is now archived and no longer maintained.

## Use cases
- style react components with inline styles
- add hover and focus states to inline styles
- handle media queries in css-in-js
- auto vendor prefix react styles
- avoid css specificity conflicts in react apps

## When to choose
- maintaining a legacy React codebase that already uses Radium
- you need a minimal, dependency-light inline styling approach for an old React version

## When to avoid
- starting a new React project - use modern CSS-in-JS or styling solutions instead
- you need server-side rendering support or modern React features
- you expect active maintenance or community support

## Facets
- artifact type: library
- maturity: abandoned
- function: css-framework, ui-components
- domain: frontend, web-development
- platform: browser
- tags: css-in-js, react, inline-styles, archived, nodejs, web-server
