HTML is written in the form of HTML elements consisting of tags
enclosed in angle brackets (like <html>,<head>,<Title>
). 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 theend tag (they are also called opening tags and closing
tags).
HyperText Markup Language is not case Sensitive.
A web browser can read HTML files and compose them into visible or
audible web pages. The browser does not display the HTML tags, but uses
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 W3C,
maintainer of both the HTML and the CSS standards, encourages the use of
CSS over explicit presentational HTML.
