History of HTML

History Of HTML:

HTML is a markup language used primarily to create hypertext Web pages, which are published on the Web and displayed in any Web browser. A markup language is a set of notations that specifies how the content should look in the browser. HTML is derived from Standard Generalized Markup Language (SGML), which is the mother language of HTML. SGML is a markup language that defies the structure of other markup languages.

HTML has evolved over the years with the introduction of improved set of standards and specification. HTML 1.0 was the fist version of HTML introduced in 1993. At that tie, there were very less people involved in designing Web sites. HTML 2.0 was introduced in 1995 and included the complete HTML 1.0 specification with additional features.

 The other versions are as follows:

• HTML 3.0

HTML 3.0 specification included new features for the Netscape Navigator browser as it became very popular. The new improvements did not work on any other browsers such as Internet Explorer. Therefore, this specification was abandoned.

• HTML 3.2

Additional browser-specific features revolutionized the need for standardization of HTML. Therefore, the World Wide Consortium (W3C) organization was formed to specify
and maintain the HTML standards. HTML 3.2 was the fist specification introduced by W3C in January 1997 and was fully supported by all the Web browsers.

• HTML 4

W3C introduced HTML 4.0 in December 1997 with the motive for facilitating support for CSS, DHTML, and JavaScript. However, HTML 4.0 prevailed for a short period and was revised, which led to HTML 4.01 specification in 1999.

• HTML 5

HTML 5 is cooperate project between the W3C and the Web Hypertext Application
Technology Working Group (WHATWG).
W3C was busy working with X HTML 2.0 and WHATWG was working with Web forms,new HTML features, and applications. In 2006, the two groups decided to work together and develop a new version of HTML.
Some basic rules for HTML 5 that were established are as follows:

• Introduction of new features should be based on HTML, CSS, DOM, and JavaScript.
• More markup should be used to replace scripting.
• HTML 5 must be device independent.
• Need for external plug-ins, such as Flash, to be reduced
• Better error handling capabilities.
• Development process should be completely visible to the public.
