Both Netscape and Microsoft have created their own versions of Dynamic HTML (DHTML). Incompatibilities between their browsers make it very difficult for web designers to use DHTML to add advanced user interface features to their sites. This is the first book that answers the question webmasters are asking more and more frequently: How can DHTML be used effectively, given the issue of incompatible browsers among users? Writing Cross-Browser Dynamic HTML focuses on answering this critical question without getting sidetracked into general HTML or XML issues. The result is a book that clearly and concisely addresses programmers' needs without overwhelming them with a cumbersome volume that tries to answer every possible question about DHTML.
Author Heather Williamson begins by introducing the fundamental concepts upon which DHTML programming is based: the Document Object Model, Cascading Style Sheets, and scripting languages. In each case, she cites the differences between the Netscape and Microsoft implementations of these features. You'll learn which features can be used safely, which must be avoided, and how to use scripting languages to overcome differences between DHTML implementations.
Williamson then moves into an in-depth discussion of how to use the knowledge of DHTML differences in real-world applicationsspecifically, as applied to a highly interactive professional website. She finishes the book by going beyond the purely technical issues to discuss how compatibility must be incorporated into the development process, especially when teams of developers are involved.
