Appendix C. Cascading Style Sheet Properties Quick Reference

In the following table, we list, in alphabetical order, all the properties defined in the World Wide Web Consortium’s Recommended Specification for Cascading Style Sheets, Level 2 (http://www.w3.org/pub/WWW/TR/REC-CSS2/).

As in other sections of this book, we use the Netscape and Internet Explorer icons to the far right of each property to show which browser supports that property. Properties with no icons currently are not supported by any browser. We also include the number of the section in this book that fully defines the property.

We include each property’s possible values, defined as either an explicit keyword (shown in constant width) or as one of these values:

rgb(red, green, blue)

where red, green, and blue are either numbers in the range 0 to 255 or percentage values indicating the brightness of that color component. Values of 255 or 100% indicate that the corresponding color component is at its brightest; values of 0 or 0% indicate that the corresponding color component is turned off completely. For example:

rgb(27, 119, 207)
rgb(50%, 75%, 0%)

are both valid color specifications.

frequency

A numeric value followed by hz or khz, indicating Hertz or kiloHertz.

length

An optional sign (either + or -), immediately followed by a number (with or without a decimal point), ...
