HTML (HyperText Markup Language) Introduction Hypertext Markup Language is a standardized system for tagging text files to achieve font, color, graphic, and hyperlink effects on World Wide Web pages. HTML (Hypertext Markup Language) is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. Two extensions (.html, .htm) are used for HTML files. HTML (Hypertext Markup Language) is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. The markup tells the Web browser how to display a Web page's words and images for the user. Each individual markup code is referred to as an element (but many people also refer to it as a tag). Some elements come in pairs that indicate when some display effect is to begin and when it is to end. Stands for "Hyper-Text Markup Language." This is the language that Web pages are written in. Also known as hypertext documents, Web pages must conform to the rules of HTML in order to be displayed correctly in a Web browser. The HTML syntax is based on a list of tags that describe the page's format and what is displayed on the Web page. Fortunately, the HTML language is relatively easy to learn. Even more fortunately (so much for good grammar), many Web development programs allow you to create Web pages using a graphical interface. These programs allow you to place objects and text on the page and the HTML code is written for you. HTML is a formal Recommendation by the World Wide Web Consortium (W3C) and is generally adhered to by the major browsers, Microsoft's Internet Explorer and Netscape's Navigator, which also provide some additional non-standard codes. The current version of HTML is HTML 4.0. However, both Internet Explorer and Netscape implement some features differently and provide non-standard extensions. Web developers using the more advanced features of HTML 4 may have to design pages for both browsers and send out the appropriate version to a user. Significant features in HTML 4 are sometimes described in general as dynamic HTML. What is sometimes referred to as HTML 5 is an extensible form of HTML called Extensible Hypertext Markup Language (XHTML).

It is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>). HTML tags most commonly come in pairs like <h1> and </h1>, although some tags represent empty elements and so are unpaired, for example <img>. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags). Web browsers can read HTML files and compose them into visible or audible web pages. Browsers do not display the HTML tags and scripts, but use them to interpret the content of the page. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language. HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts written in languages such as JavaScript which affect the behavior of HTML web pages. Web browsers can also refer to Cascading Style Sheets (CSS) to define the look and layout of text and other material. The World Wide Web Consortium (W3C), maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicit presentational HTML. Developed by Tim Berners-Lee in 1990, HTML is short for HyperText Markup Language. HTML is used to create electronic documents (called pages) that are displayed on the World Wide Web. Each page contains a series of connections to other pages called hyperlinks. Every web page you see on the Internet is written using one version of HTML code or another. HTML code ensures proper formatting of text and images by enabling your Internet browser to interpret them properly. Without HTML, a browser would not know how to display text as elements or bring load images. HyperText Markup Language: a set of standards, a variety of SGML, used to tag the elements of a hypertext document. It is the standard protocol for formatting and displaying documents on the World Wide Web. hypertext markup language: a text description language that is used for electronic publishing, especially on the Internet A markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web. An abbreviation for Hypertext Markup Language. This is the basic format for language that is used to construct the World Wide Web. HTML is a Standard text based computer language for creating electronic (hypertext) documents for the web or offline uses. Being a 'markup' language, the value of HTML lies not so much in designing a visual structure (fonts, line spacing, layout, etc.) of an electronic document but in formulating its logical structure. The logical structure permits 'intelligent' information processing that is a prerequisite for the information's organization, indexation, communication, and discovery on the web. HTML supports inclusion of audio, video, and animation into an electronic document through helper software such as ActiveX, Java applets, Quick-Time. HTML is an acronym for Hypertext Markup Language which is defined as the coding used to include color, language, and graphics on a webpage. Examples of HTML tags are --- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 HTML <head> Tag HTML <title> Tag HTML <body> Tag HTML <heading> Tag HTML <p> Tag HTML <center> Tag HTML <br> Tag HTML <hr> Tag HTML Text Formatting Tag (<b>, <em>, <i>, <small>, <strong>, <sub>, <sup>, <ins>, <del>, <mark>, <u>, <strike>, <big>, <pre>, <font color>, <font size>, <font face>, <blockquote>, <center>, <tt>) HTML Styles ( Background-color attribute, Color attribute, Font-family attribute, Font-family attribute, Font-size attribute, Textalign attribute) HTML Links (<a> tag, href attribute) HTML Images (<img> tag, src attribute, alt attribute) HTML C,omments ( <!> tag) HTML Lists < Unordered Lists<ul>, Ordered Lists<ol>, Description List (<dl>, <dt>, <dd>), Nested Lists, <li> tag) HTML Tables ( <tables>, <tr>, <td>, <th> ) HTML Frames (<frameset>)
