## What it is
The official W3C CSS Working Group repository containing editor's drafts of CSS specifications, written in Bikeshed. It also hosts the issue tracker where CSS specification changes and bugs are discussed.

## Use cases

## When to choose

- you want to participate in CSS standards development
- you're researching browser CSS feature behavior at the spec level

## When to avoid
- you want a CSS framework or library for styling websites
