The World Wide Web (WWW) acts as a multimedia Internet, navigable via Web browsers. Web browsers (Mosaic, Netscape, Cello, WinWeb, etc.) read files treated in HyperText Mark-up Language (HTML) and display interactive pages to users. Teachers with computer-mediated classrooms or labs can use HTML and Web browsers to create multimedia presentations for their classes. Files required for HTML, including text, graphics, and other multimedia, are discussed. The process involves using text files to create HTML documents containing coding-embedded HTML commands. HTML commands are the language used to mark up text to make it interactive and "pretty." The most common HTML codes ("tags") for making text pretty are listed and defined. Additional codes are defined which are needed to turn the text into an interactive, multimedia experience. Appendices include sample text from a Web document and some Internet sites of interest to Web builders. (MAS)
