On the Web, the term "multimedia" refers to everything from a moving graphic and background audio on a page to a full-blown, high-quality video feed. Because such a broad range of features fits into this category, many separate tools and solutions have been developed to play multimedia, and modern browsers provide a wide variety of multimedia options. This chapter is an overview of some types of multimedia. It covers common cross browser ways to use multimedia on Web pages, shows how to create media files, and offers guidelines for planning the use of media on your Web pages.
