4. 3.1 Introduction to HTML
HTML stands for Hyper Text Markup
Language
An HTML file is a text file containing small
markup tags
The markup tags tell the Web browser
how to display the page
An HTML file must have an htm or html
file extension
An HTML file can be created using a
simple text editor

7. 3.2 HTML Elements
HTML tags are used to mark-up HTML elements
HTML tags are surrounded by the two characters < and >
The surrounding characters are called angle brackets
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
The text between the start and end tags is the element
content
HTML tags are not case sensitive, <b> means the same as
<B>

38. Summary
This tutorial has taught you how to use
HTML to create your own web site.
HTML is the universal markup language for
the Web.
HTML lets you format text, add graphics,
create links, input forms, frames and
tables, etc., and save it all in a text file
that any browser can read and display.
The key to HTML is the tags, which
indicates what content is coming up.

39. What's Next?
CSS
CSS is used to control the style and layout of
multiple Web pages all at once.
With CSS, all formatting can be removed from
the HTML document and stored in a separate
file.
JavaScript
JavaScript can make your web site more
dynamic.
A static web site is nice when you just want to
show flat content, but a dynamic web site can
react to events and allow user interaction.
