A Brief History of HTML

The first version of HTML was written in 1993 by Tim Berners-Lee. Since then, many different versions of HTML have appeared. The most widely used version in the 2000s was HTML 4.01, which became an official standard in December 1999.

Another version, XHTML, is a rewrite of HTML into the XML language. XML is a standard markup language for creating other markup languages. There are hundreds of XML languages ..

in use today, including GML (Geographic Markup Language), MathML, MusicML, and RSS (Really Simple Syndication). Because each of these languages ..

is written in a common language (XML), their content can be easily shared between applications. This makes XML potentially very powerful, so it’s no surprise that the W3C created an XML version of HTML called XHTML. XHTML became an official standard in 2000 and was updated in 2002. XHTML is very similar to HTML, but with stricter rules. All XML languages ..require strict rules without which interoperability between applications would be impossible. In Unit 2, you will learn more about the differences between HTML and XHTML.

Most pages on the Web today are created using HTML 4.01 or XHTML 1.0. However, in recent years, the W3C (in collaboration with another organization, the WHATWG) has been working on an entirely new version of HTML, HTML5.

Currently (2011) HTML5 is still a draft specification and not yet an official standard. However, it is already widely supported by browsers and other web-enabled devices and is the way of the future. Therefore, HTML5 is the primary language taught in this course.

Application of HTML

As mentioned earlier, HTML is one of the most widely used languages on the Internet. I will list some of them here:

Game Development — HTML5 provides native support for rich experiences and is now useful in game development as well.

Web Development — HTML is used to create pages that are rendered on the web. Almost every web page contains HTML tags to render its details in the browser.

Internet Navigation — HTML provides tags for navigating from one page to another, typically for Internet navigation.

Responsive UI — Thanks to responsive design strategies, HTML pages can now run on any platform, mobile, tab, desktop or laptop.

Offline Support Once loaded, HTML pages can be used offline on the machine, no internet connection required.
