Cascading Style Sheets
One relatively stable feature of DHTML is CSS. In looking at the two browsers and Windows and Macintosh operating systems, you find some differences, but not many. This is especially true with IE6 and NN6. In this section, I want to go over some of the more critical visual elements that are part of CSS. CSS has an aural component that is not addressed in this book, as well as many other features that make CSS an important designer’s tool. One highly regarded source is Cascading Style Sheets 2.0 Programmer’s Reference, by Eric A. Meyer (Osborne, 2001). Online, you cannot do better than the CSS2 standard, at http://www.w3.org/TR/REC-CSS2/about.html. Here, though, you need to understand something about the basics.
