What Does Cascading Style Sheets Level 2 Mean?
Cascading Style Sheets Level 2 (CSS2) is the second version of cascading style sheets developed by W3C. It’s a declarative language used to enhance the hyperextensive text markup language. CSS2 is a subset of Cascading Style Sheets Level 1 and has enhanced capabilities like:
- Media types concept
- Aural style sheets
- Features for internationalization
- Extended font selection
- Automatic numbering and generated content
- Dynamic outlines
- Capability to control content overflow, clipping
- Absolute, fixed and relative positioning
- Extended selector mechanism
Currently, W3C does not provide any CSS2 recommendations. CSS2 have backward compatibility, so all valid CSS1 is also valid CSS2.
