Contents Appendix B. Changes from CSS1 B.1 New functionality . . . . . . . . . . . . 293 . B.2 Updated descriptions . . . . . . . . . . . 294 . B.3 Semantic changes from CSS1 . . . . . . . . . 294 . This appendix is informative, not normative. CSS2 builds on CSS1 and all valid CSS1 style sheets are valid CSS2 style sheets. The changes between the CSS1 specification (see [CSS1]) and this specification fall into three groups: new functionality, updated descriptions of CSS1 functionality, and changes to CSS1. B.1 New functionality In addition to the functionality of CSS1, CSS2 supports: The concept of media types [p. 77] . The ’inherit’ [p. 71] value for all properties. Paged media [p. 175] Aural style sheets [p. 277] Several internationalization features, including list numbering styles [p. 168] , support for bidirectional text [p. 127] , and support for language-sensitive quotation marks [p. 157] . An extended font selection [p. 212] mechanism, including intelligent matching, synthesis, and downloadable fonts. Also, the concept of system fonts has been is introduced, and a new property, ’font-size-adjust’, has been added. Tables [p. 245] , including new values on ’display’ and ’vertical-align’. Relative [p. 107] and absolute positioning [p. 113] , including fixed positioning [p. 113] . New box types (along with block and inline): compact [p. 99] and run-in [p. 100] . The ability to control content overflow [p. 145] , clipping [p. 147] , and visibility [p. 149] in the visual formatting model. The ability to specify minimum and maximum widths [p. 136] and heights [p. 140] in the visual formatting model. An extended selector [p. 53] mechanism, including child selectors, adjacent selectors, and attribute selectors. Generated content [p. 153] , counters and automatic numbering [p. 160] , and markers [p. 164] . Text shadows, through the new ’text-shadow’ property. Several new pseudo-classes [p. 61] , :first-child, :hover, :focus, :lang. System colors [p. 272] and fonts [p. 274] . Cursors [p. 271] . 293
