Hyper Text Markup Language (HTML) is the main markup language for creating web pagesand other information that can be displayed in a web browser.
HTML is written in the form of HTML elements consisting of tags enclosed in angle bracketswithin the web page content. HTML tags most commonly come in pairscalled opening tag and closing tag, although some tags, known as empty elements,are unpaired. The first tag in a pair is the start tag, and the second tag isthe end tag (they are also called opening tags and closing tags).In between these tags web designers can add text, tags, comments and othertypes of text-based content.
The purpose of a web browser is to read HTML documents and compose theminto visible or audible web pages. The browser does not display the HTML tags,but uses the tags to interpret the content of the page.
Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance andlayout of text and other material. The W3C, maintainer of both the HTML and the CSS standards,encourages the use of CSS over explicit presentational HTML markup.
