HyperText Markup Language (HTML)

The coding language used to create Hypertext documents for use on the World Wide Web.

It provides a means to describe the structure of text-based information in a document - by denoting certain text as links, headings, paragraphs, lists, and so on - and to supplement that text with interactive forms, embedded images, and other objects. HTML is written in the form of tags, surrounded by angle brackets. HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code (such as JavaScript) which can affect the behaviour of Web browsers and other HTML processors.

HTML is loosely based on a more comprehensive system for markup called SGML, and is expected to eventually be replaced by XML-based XHTML standards.
