HTML or HyperText Markup Language is the main markup language for creatingweb
pages and 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
brackets (like <html>), within the web page content. HTML
tags most commonly come in pairs like <h1> and </h1>, although some tags
represent empty elementsand 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). In between
these tags web designers can add text, further tags, comments and other types of
text-based content.
The purpose of a web
browser is to read HTML documents and compose them into
visible or audible web pages. The browser does not display the HTML
tags, but uses the tags to interpret the content of the page.
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 embedscripts 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 W3C, maintainer of both the
HTML and the CSS standards, encourages the use of CSS over explicit
presentational HTML.
