Notes
Tagging standard
- Every page should have the tag "CSS".
- CSS properties belonging to a group have the tag of that group. E.g. "CSS Flexible Boxes"
Wishlist
Ideas for future projects or things the ideal CSS documentation should have:
- Compatibility summary list
- CSS variables
- CSS to style forms (non-standard, including Chrome and IE specific styling)
- Better CSS flexbox documentation
