Detailed Description

The w3c/csswg-drafts repository is a collection of CSS Working Group Editor's Drafts that serves as the authoritative source for evolving CSS specifications.

The repository addresses the need to maintain and publish multiple CSS specifications in draft form before they reach official recommendation status. It uses Bikeshed as its primary language for writing specifications, and employs GitHub Actions workflows to automate the building and deployment of these drafts. The main workflow builds the entire repository of Editor's Drafts along with a summary page, processes Issues-List files and Markdown documents, and deploys results to the repository's gh-pages branch. Individual specifications can also be auto-published through generated workflow files that are created and maintained programmatically rather than by hand.

This repository is essential for anyone involved in CSS standards development or tracking the evolution of CSS features. It suits organizations and individuals who need access to the latest CSS specifications before they become official recommendations, as well as those implementing experimental CSS features. The repository provides a transparent view into ongoing CSS standardization work and serves as the primary reference for CSS Working Group proposals.

The project maintains active development with regular updates to multiple specifications across the repository. Workflow automation is carefully managed through a generation script that creates individual publish workflows, ensuring consistency and reducing manual maintenance burden. The repository handles both specification documents and associated metadata like issues lists, indicating a comprehensive approach to managing the full lifecycle of specification drafts.
