## What it is
CSSX is a set of tools (transpiler, client-side library, CLI, and bundler plugins) for writing vanilla CSS inside JavaScript, generating real stylesheets injected into the DOM rather than inline styles. It includes a JSX-like CSSX language with dynamic values and integrations for Webpack, Gulp, Browserify, Rollup, and React.

## Use cases
- write css in javascript
- generate stylesheets dynamically at runtime
- transpile cssx code with webpack or gulp
- manage component styles without inline styles
- inject styles into the dom from js

## When to choose
- you want vanilla CSS syntax inside JavaScript with dynamic values
- you need runtime style generation via injected stylesheets
- you're maintaining an existing codebase already using CSSX

## When to avoid
- starting a new project - the project is unmaintained since 2016
- you want a modern, actively maintained CSS-in-JS solution
- you prefer static CSS files or CSS modules
