HTML or Hyper
Text Markup Language is
the main markup
language for
creating web
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
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). 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 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 W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicit presentational HTML.
