## What it is
A Node.js CSS parser and stringifier that converts CSS source code into an AST and back, with support for source maps and compression. It is now in maintenance mode with no planned changes; the maintainers recommend migrating to @adobe/css-tools.

## Use cases
- parse css into an ast in node.js
- stringify a css ast back to a stylesheet
- generate source maps for transformed css
- compress or minify css output
- programmatically inspect css rules and declarations

## When to choose
- you need a simple, battle-tested CSS parser/stringifier for a legacy Node.js pipeline
- you only need basic parse/stringify with source map support and no active development

## When to avoid
- you are starting a new project - use @adobe/css-tools or a modern alternative like postcss instead
- you need ongoing bug fixes or new CSS syntax features
- you need browser-side parsing

- artifact type: library
