HTML 4.0 was the final version of the Hypertext Markup Language (HTML) before the Extensible Markup Language (XHTML) and remains the set of markup on which most large Web sites today are based. Like all HTML levels, HTML 4.0 was the official "recommendation" of the World Wide Web Consortium (W3C), the group that suggests industry standards for the Web. The purpose of a web browser is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page. This course teaches you the basic to more advanced HTLM tags used in the development of web pages.
