Tim Berners –Lee invents the Web
using HTML as its publishing language in 1989.
Tim had the idea of allowing researchers from different sites in the
world to organize and pool together information. But far from simply making
available a large number of research documents as files that could be
downloaded to individual computers, he suggested that you could actually link
the text in the files themselves. This
means, while researching one subject, the researcher would be able to quickly
display another subject. Tim realized by
linking research together using a form of hypertext, these tasks could be
performed by using buttons on the screen.
His idea did not become popular until the 1990’s. HTML is the abbreviation for Hyper Text
Markup Language. It is the standard
markup language used to create web pages.
HTML is written in the form of HTML elements consisting of tags
enclosed in angle
brackets (like
<html>). 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). The idea of a web browser is
to read HTML documents and produce them into visible or audio web pages. The browser does not show the HTML tags, but
uses the tags to interpret the content of the page. HTML is the basis for all types of
websites. It is the backbone and
stepping stone to any birth of a website.
HTML defines several data types for element content, such as
script data and stylesheet data, and many types for attribute values, including
IDs, names, URIs, numbers, units of length, languages, media descriptors,
colors, character encodings, dates and times, and so on. All of these data types are specializations of
character data. HTML documents can be
delivered by the same means as any other computer file.
The World Wide Web is composed primarily of HTML
documents transmitted from web servers to web browsers using the Hypertext
Transfer Protocol
(HTTP). However, HTTP is used to serve images, sound, and other content, in
addition to HTML. To allow the web browser to know how to handle each document
it receives, other information is transmitted along with the document. HTML
allows images
and objects to
be embedded and can be used to create interactive forms.
It provides a means to generate structured
documents by
representing essential interpretation for text such as headings, paragraphs,
lists, links, quotes and other items. It can insert 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 describe the look and layout of text and other material. The W3C,
maintainer of both the HTML and the CSS standards, boosts the use of CSS over
obvious arrangement HTML. Without the use of an HTML, access to the internet we
now know would not exist. If it was not
for people like Berners, the web would not exist in the fashion it does
today.
