HTML
(Hypertext Markup Language) is the set of markup symbols or codes inserted in a
file intended for display on a World Wide Web browser page. The markup tells
the Web browser how to display a Web page's words and images for the user. Each
individual markup code is referred to as an element (but many people also refer
to it as a tag). Some elements come in pairs that indicate when some display
effect is to begin and when it is to end.
HTML is a
formal Recommendation by the World Wide Web Consortium (W3C) and is generally
adhered to by the major browsers, Microsoft's Internet Explorer and Netscape's
Navigator, which also provide some additional non-standard codes. The current
version of HTML is HTML 4.0. However, both Internet Explorer and Netscape
implement some features differently and provide non-standard extensions. Web
developers using the more advanced features of HTML 4 may have to design pages
for both browsers and send out the appropriate version to a user. Significant
features in HTML 4 are sometimes described in general as dynamic HTML. What is
sometimes referred to as HTML 5 is an extensible form of HTML called Extensible
Hypertext Markup Language (XHTML).
