CSS Cookbook, 3rd Edition

Appendix B. CSS 2.1 Properties and Proprietary Extensions

This appendix contains several tables. Table B-1 lists CSS properties from W3C’s CSS 2.1 specification (see http://www.w3.org/TR/CSS21). It lists the property’s values, initial value, what the property applies to, whether the values in the property are inherited, whether the property accepts percentages, and the property’s media group.

Table B-2 lists Microsoft’s proprietary extensions to the specifications. These properties will not validate if you run them through a validator and they will appear successfully only in a browser built by Microsoft. Your mileage will vary with the use of these extensions.

As of this writing, Mozilla’s proprietary extensions that are available in Mozilla, Firefox, and Netscape Navigator 6 and later browsers are not fully documented. Table B-3 lists some extensions that are documented from Mozilla’s developers’ website. Check the site for a complete list of the extensions, at http://developer.mozilla.org/en/docs/CSS_Reference:Mozilla_Extensions.
