Encyclopedia - HTML


    (HyperText Markup Language) The standard document format for Web pages, defined by the Internet Engineering Task Force (IETF). Every Web page contains HTML tags (codes) embedded in the text that define the page layout, fonts and hypertext links. The link contains the URL (address) of another Web page on that same server or any server worldwide, hence "World Wide" Web. The HTML tags also define the graphic elements on the page, each of which is a separate file on a local or remote server.

    Since its inception by Tim Berners-Lee in the early 1990s, new versions of HTML have added features such as interactive forms, blinking text, custom backgrounds and tables of contents. To keep current, vendors have to update their Web browsers to accommodate the new tags; however, each new HTML version is backward compatible (mostly) with older versions.

    HTML Is Not a Programming Language

    HTML was conceived as a simple markup language to display documents on the Web, and a markup language (the ML in HTML) can be thought of as a "presentation language." There is no "if this-do that" in HTML like there is in C/C++, Java and JavaScript. Therefore, in order to make Web pages behave like applications, JavaScript programming code is embedded within the HTML.

    HTML5 Is a Programming Language

    Version 5 of HTML formalized the use of JavaScript and, as a result, HTML can be considered a Web application development language. Among other enhancements, HTML5 added support for audio and video, which otherwise requires auxiliary software such as a media player and Flash.
