Sometimes you need to add Multimedia on the web like sound, music, videos, movies, and animations.
Multimedia comes in many different formats. It can be almost anything you can hear or see. For Examples: Pictures, music, sound, videos, records, films, animations, and many more.
Web pages often contains multimedia tags of different types and formats.
The first web browsers had support for text only and limited to a single font in a single color. Later came browsers with support for colors and fonts, and even support for pictures.
The support for sounds, animations, and videos is handled differently by various browsers. Different types and formats are supported, and some formats requires extra helper programs (plug-ins) to work.
Hopefully this will become history. HTML5 multimedia promises an easier future for multimedia.
Multimedia tags (like audios or videos) are stored in media files.
The most common way to discover the type of a file, is to look at the file extension. When a browser sees the file extension .htm or .html, it will treat the file as an HTML file. The .xml extension indicates an XML file, and the .css extension indicates a style sheet file. Pictures are recognized by extensions like .gif, .png and .jpg
Multimedia files also have their own formats and different extensions like: .swf, .wav, .mp3, .mp4, .mpg, .wmv, and .avi
