How is HTML5 downloaded?
HTML5 isn't something you download. HTML is the language for
creating Web pages and HTML5 is the latest version that is being
devised by Web standards organizations. To use HTML5, you can write
HTML5 instructions (known as tags) in a text editor, save the text
file, and then open the file in a Web browser that supports HTML5.
As of January 2011, the major Web browsers such as Internet
Explorer, Firefox, Safari, and Chrome are beginning to support
HTML5 features. For more information about HTML5, see the Related
