History of HTML
Where did HTML – and for that matter, web pages –come from? It’s
worth taking a look at HTML’s history, and I’ll do that in overview here. The
first person to actually use the word hypertext was Ted Nelson in the 1960s.
Was he a computer expert? No, his specialties were philosophy and sociology
We all know the result as implemented in modern Web browsers with
hyperlinks you can move from location to location just by clicking a link.
Although it took a long time to catch on, there’s simply no doubting its
Tim Berners Lee who created the first web server, came up with the term
HTML , the term HTTP (Hypertext Transport Protocol, which specifies how

hypertext is sent on the Internet), and the term URL(Uniform Resource
Locator) to represent a World Wide Web address (more on URLs in a few
To create HTML, Tim Berners-Lee knew that the would need a markup
language, so he chose SGML (Standard Generalized Markup Language), which
was a general markup language that had been around for a longtime and was
already in use on computers for specialized applications. Using SGML, you can
define markup languages, specifying their rules and grammar. Tim Bernerrs-
Lee created DTD for HTML specifying the early syntax of HTML, and so
HTML and therefore web pages, were born.
What’s HTML All About?
HTML (Hypertext Markup Language) is the language you use to create
Web pages. Left to themselves, Web browsers would take the text and images
in your Web page and wrap them up into what looks like a single paragraph
without any line breaks. With HTML , you act much like an editor does,
marking u a age to indicates its format, telling the Web browser where you
want a new line to begin or how you want text or images aligned, an more. In
other words, HTML is all about specifying the structure and format of your
Before seeing any Web pages, we’re going to get right to the HTML.
This Web page is a simple one. It displays the text “Web page number one!” in
a Web browser’s title bar and the text “Welcome to HTML~” in the Web
What HTML Editors Are Available?
There are great number of HTML editors available for you to use in
creating Web pages. Here’s starter list:
• Adobe PageMill (http://adobe.com) an editor that helps automate the
whole process of site design and implementation.
• Allaire’s HomeSite (www.allaire.com) A simple, but powerful, editor
• American Cybernetics Multi-Edit (www.amcyber.com) An HTML editor
that works well for programmers.

• Microsoft Frontpage (www.microsoft.com) an editor contained in a
powerful package than integrates directly with your web site.
• Netscape Composer (www.netscape.com) and editor that comes with the
Netscape communicator, more or less WYSIWYG. It is easy to use, but
HTML is not a procedural programming language like C,
Fortran, Cobal. It is a markup language that identifies the elements of a page so
that a browser can render the page on the screen.
HTML is used to format text & information. This marking up of
information is different from the intent of traditional programming languages,
which is to perform actions in the designated order.
In HTML text is markup with elements, delineated by tags that are key
words contain in pairs of angle brackets.
