## What it is
Atomizer is a tool and library for creating Atomic CSS, generating a static stylesheet from single-purpose utility classes like D(f) used in your markup. It is unopinionated, ships no CSS of its own, and integrates with task runners and bundlers via plugins for Grunt, Gulp, Webpack, and others.

## Use cases
- generate atomic css from class names in my templates
- utility-first css for a large react or ember app
- create small reusable css that scales with my website
- replace tailwind with an unopinionated atomic css tool
- scan markup and emit only the css classes actually used
- integrate atomic css generation into webpack or gulp build

## When to avoid
- you want a batteries-included design system with prebuilt components like Bootstrap
- you prefer Tailwind CSS conventions and its ecosystem
- your project has no build step to run the class-scanning generator

## Facets
- artifact type: library
- maturity: active
- function: css-framework, build-tool, templating
- domain: web-development, frontend, web-design
- platform: cross-platform
