What are the differences between CSS1 and CSS2?

Level 2 Cascading Style Sheets, generally referred to by the abbreviation CSS2, are backwards compatible with Level 1 style sheets (CSS1).  This is to say that CSS2 supports the same definitions that are supported by CSS1 and adds new definitions.  A brief summary of the additions follows:

1. Support for alternative media types
   Dedicated support for displays other than your computer's screen, including text readers, braille and graphical printers
   
   
2. Better internationalization
   Support for non-English list styles, quotation marks and bi-directional text
   
   
3. Content control refinements
   Added support for colors, fonts, positioning, dimensions, visibility, outlines and other content display attributes
   
   
4. Better access to content structure
   Support for generated content, pseudo-classes for relative positioning, counters and markers
   
   
5. Cursors
   Support for a standardized set of mouse cursor types
