Chapter 3. Digging Below The Surface

This chapter completes our look at the "mechanics" of CSS: the background you need to have to work with the technology. It covers six major topics:

• Quick review of the three methods for assigning CSS properties to HTML documents

• Use of shorthand properties to group values for a related set of properties in a single statement

• Workings of the inheritance mechanism in style sheets

• Structure of a style, including variations on the use of selectors for determining with great precision exactly what is affected by a style

• Units and values that can appear in styles to express sizes, locations, and other properties, and how they are used

• CSS comments, which can be used to place human-readable notes in your CSS code
