The remainder of this chapter lists all the properties defined in the World Wide Web Consortium's Recommended Specification for Cascading Style Sheets, Level 1 (http://www.w3.org/pub/WWW/TR/REC-CSS1). All browsers do not implement all properties fully, and some simply do not work correctly. As in the HTML reference, we use the Netscape and Internet Explorer icons to show which browser supports that property. Properties with no icons are not currently supported by these browsers.
The following list includes 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.

In these cases, a list consists of one or more of the allowed values, separated by commas. The standard defines a default value for most properties. The default property is listed in the top syntax line for the property. Additional allowed values are listed beneath each description.
