HTML
stands for Hyper Text Markup Language.
HTML is not a programming language, it is a markup language. A markup language
is a set of markup tags. The
markup tags describe how text should be displayed.
HTML Markup
Tags: HTML markup tags are usually called HTML tags
- HTML tags
are keywords surrounded by angle
brackets like <html>
- HTML tags
normally come in pairs like
<b> and </b>
- The first
tag in a pair is the start tag,
the second tag is the end tag
Note: The start and end tags are also called
the opening and closing tags.
HTML
Files: When a browser displays a web page, it will not display the markup tags.
The browser uses the markup tags to understand the layout of the page.
- An HTML
file is a text file with HTML tags
- An HTML
file name must end with .htm
or .html
- An HTML
file can be created using a simple
text editor
- An
HTML file is often called an HTML
document or a Web Page
HTML Versions:
a) HTML 2.0:
HTML 2.0 was developed by the Internet Engineering Task Force HTML Working
Group in 1996. HTML 2.0 is an outdated version of HTML. For a Web developer
there is no need to study the HTML 2.0 standard.
b) HTML 3.2:
HTML 3.2 became a W3C Recommendation 14. January 1997. HTML 3.2 contained new
features such as fonts, tables, applets, superscripts, subscripts and more, to
the existing HTML 2.0 standard. One of the elements added to the HTML 3.2
standard, was the <font> tag. This tag introduced unnecessary complexity
to the important task of separating HTML content (text) from its presentation
(style). The <font> tag became deprecated in HTML 4.0.
c) HTML 4.0:
HTML 4.0 became a W3C Recommendation 18. December 1997. A second release was
issued on 24. April 1998 with only some editorial corrections. The most
important feature of HTML 4.0 was the introduction of style sheets (CSS).
