HTML Utopia: Chapter 5: Building the Skeleton
Most books on CSS begin by teaching you how to deal with the bits and pieces of a Web page: fonts, colors, lists, and the like. Then, they move on to explaining the broader issues associated with CSS Positioning (CSS-P), which affect the layout of pages rather than the appearance of individual elements.

This chapter focuses specifically on creating the basic structural layout of a Web page or site using CSS. In it, I’ll discuss multi-column layouts—both in general and very specifically—as they relate to the Footbag Freaks site. I’ll teach you about boxes, borders, and the famous Box Model of CSS design. I’ll delve into the intricacies of creating and using two- and three-column page layouts, and into the mysteries of floating objects. I’ll guide you through the process of creating dummy layouts for the pages you’ll encounter in the Footbag Freaks project, and in other projects you may create.
