HTML

Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a . It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.
Web browsers receive HTML documents from a or from local storage and the documents into multimedia web pages. HTML describes the structure of a web page and originally included cues for the appearance of the document.
==Function==
s are the building blocks of HTML pages. With HTML constructs, and other objects such as may be embedded into the rendered page. HTML provides a means to create s by denoting structural for text such as headings, paragraphs, lists, , quotes and other items. HTML elements are delineated by tags, written using . Tags such as <img /> and <input /> directly introduce content into the page. Other tags such as surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.
HTML can embed programs written in a such as , which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML as of 1997.

In 1980, physicist Tim Berners-Lee, a contractor at , proposed and prototyped , a system for CERN researchers to use and share documents. In 1989, Berners-Lee wrote a memo proposing an -based system.Tim Berners-Lee, "Information Management: A Proposal." CERN (March 1989, May 1990). W3.org Berners-Lee specified HTML and wrote the browser and server software in late 1990. That year, Berners-Lee and CERN data systems engineer collaborated on a joint request for funding, but the project was not formally adopted by CERN. In his personal notesTim Berners-Lee, "Design Issues" from 1990 he listedTim Berners-Lee, "Uses" "some of the many areas in which hypertext is used" and put an encyclopedia first. Berners-Lee prototyped the world's first web pages on a NeXT Computer System.
The first publicly available description of HTML was a document called "HTML Tags", first mentioned on the Internet by Tim Berners-Lee in late 1991. It describes 18 elements comprising the initial, relatively simple design of HTML. Except for the hyperlink tag, these were strongly influenced by , an in-house Standard Generalized Markup Language (SGML)-based documentation format at CERN. Eleven of these elements still exist in HTML 4.
