Microsoft® Dynamic HTML technology helps to remove these barriers for content providers and offers users more engaging and interactive Web pages. Dynamic HTML provides authors with enhanced creative control so they can manipulate any page element at any time. Dynamic HTML is also the easiest way to make Web pages interactive, using open, standards-based technologies. Microsoft is working with the World Wide Web Consortium (W3C) to help ensure interoperability and support for users on multiple systems with different browsers.
Dynamic HTML builds upon existing HTML standards to expand the possibilities of Web page design, presentation, and interaction. Ultimately, mastering DHTML will allow you to build Web-based applications, rather than mere portraits of data. Because DHTML is essentially an "added value" technology, you should be rather familiar with basic Web page design using traditional HTML specifications. Experience with JavaScript programming is also necessary to employ the potential of DHTML.
