HyperText Markup Language (HTML), is the predominant markup language for the creation of Web pages. By working in the background, html provides the formatting that makes pages both attractive and readable. HTML code is used to denote certain text as bold, italic and underlined. HTML also produces headings, paragraphs, lists, and so on within a document, and supplements text with interactive forms, embedded images, and other objects.
HTML is written in the form of tags, surrounded by less-than (). For example, b surrounded by is a 'tag' that turns on the bold type. HTML can also include embedded scripting language code which can affect the behavior of Web browsers and other HTML processors.
