HTML or Hypertext Mark-up Language is the main mark-up
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 (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 ad 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 behaviour of HTML web pages.
Web browsers can also refer to Cascading style sheet (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
