Hologram is a Ruby gem that parses specially formatted /*doc */ comments in CSS (and other source files) and generates static HTML style guide documentation. Documentation is written inline using YAML metadata and Markdown, with code blocks marked as examples rendered both as live HTML and as escaped code.

Use cases

• generate a style guide from CSS comments
• build living style guide documentation for a design system
• document CSS components with markdown and html examples
• turn inline CSS documentation into a browsable website
• create a component library reference site

When to choose

• you maintain a CSS codebase and want documentation living next to the styles
• you want a self-hosted, customizable style guide without a hosted service
• your team works in Ruby and prefers gem-based tooling

When to avoid

• you use modern tooling like Storybook or Style Dictionary
• you need active development and recent community support
• you want JavaScript component documentation rather than CSS-centric docs
