Multimedia on the web refers to sound effects, music, video, and animation.
Modern web browsers already support many multimedia formats.
What is multimedia?
Multimedia comes from many different formats. It can be anything you hear or see, text, pictures, music, sound effects, recordings, movies, animations, and more.
On the Internet, you will often find multimedia elements embedded in web pages, and modern browsers already support multiple multimedia formats.
In this tutorial, you will learn about the different multimedia formats and how to use them in your web pages.
The first Internet browser only supported text, and even text support was limited to a single font and a single color. Browsers supporting colors, fonts, and text styles were born, and image support was added.
Different browsers handle support for sound effects, animation, and video in different ways. Some elements can be handled inline, and some require additional plugins.
You will learn more about plugins in the following chapters.
Format Multimedia elements such as video and audio are stored in media files.
The most common way to determine the type of media is to look at the file extension. When the browser gets the file extension .htm or .html, it assumes that the file is an HTML page. The .xml extension indicates an XML file, and the .css extension indicates a style sheet. Picture formats are identified by .gif or .jpg.
Multimedia element elements also have file formats with different extensions, such as .swf, .wmv, .mp3, and .mp4.
