HTML, short for Hypertext Markup Language, is the predominant markup language for the creation of web pages. It provides a means to describe the structure of text-based information in a document — by denoting certain text as 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 labels (known as tags), surrounded by less-than and greater-than signs. Technically is HTML an application of the Standard Generalized Markup Language (SGML). The HTML development has been stopped since 1999. It's successor, the XHTML, is an application of the Extensible Markup Language (XML).
