3.5. Of Style Sheets, Elements, Attributes, and Values

Regardless of the syntax you use to define a style sheet, the basic concepts are the same. A style sheet is a collection of one or more rules. Each rule has two parts to it:

In other words, each rule defines a particular look and feel and the item(s) in the document that are to be governed by that look and feel.

3.5.1. Style Attributes

A style attribute is the name of a (usually) visible property of a piece of content on the page. An attribute such as color can apply to any element because that color can be applied to foreground content, such as text. Some attributes, such as borders and margins, can apply only to elements rendered as blocks on the page—they have a clear beginning and ending in both the HTML source code and in the layout. In their conservative approaches to claiming standards support, IE 6 and Netscape 6 promise full implementations of CSS1 (while both browsers support a lot of CSS2). To help you visualize the range of style options available as a common denominator, Table 3-1 shows a summary of CSS1 attributes grouped by category. You can find details of all CSS style sheet attributes in Chapter 11.
