CSS Reference is a free visual guide to the most popular CSS properties, built as a Jekyll static site and published at cssreference.io. It explains properties like flexbox, grid, animations, backgrounds, and typography with illustrated and animated examples.

Use cases

  • learn CSS properties with visual examples
  • look up how a CSS property like flex-grow or grid-auto-flow works
  • find illustrated explanations of animations and transitions
  • teach CSS to beginners with animated demos
  • browse popular CSS properties by category like flexbox, grid, and typography

When to choose

  • you want a free, visual, example-driven CSS reference
  • you learn better from animated illustrations than text specs
  • you need a quick lookup for common CSS properties

When to avoid

  • you need exhaustive coverage of every CSS property or the latest specs
  • you need an interactive playground to write and test code
  • you need MDN-level technical detail on browser compatibility
