HTML as a Markup Language
html for image
HTML is a subset of SGML (Standard General Markup Language) with more forgiving rules that are not followed for XHTML and XML (also subsets).
A markup language is very different from a programming language. Program files and data files exist separately in traditional applications. In a markup language, the instructions and the data reside in the same file. In addition, HTML does not provide data structures or internal logic, as do programming languages such as C and Pascal.
HTML is an application of SGML. It has fewer language elements than SGML, it is easier to use and has become the standard method of encoding information for Web documents. As with GML, HTML facilitates data exchange through a common document format across different types of computer systems and networks on the Web.

Whereas SGML is used specifically to define context as opposed to appearance, HTML has evolved into both a contextual and a formatting language. By applying a heading style to text using HTML, for example, you are not only marking that text contextually as an important line that begins a new section; you are also applying the visual formatting elements of boldface and a larger font size.
