Intro to HTML
HTML stands for Hyper-Text Markup
Language
It is a subset of SGML (Standard
Generalized Markup Language)
Historically HTML and SGML are
presentational styles and not well adapted to
interactivity
HTML Basics
HTML files are text files and can be created in
ANY text editor
Visual effects are created by the way that Web
Browser software interprets the text.
Effects are created by enclosing text with special
tags
The list of tags is relatively short and worth
learningregardless of the HTML editing
software there are always times that you need to
tweak your HTML
HTML Basics (contd)
Tags resemble characters enclosed in pointy
bracketse.g. <p>
There are opening tags, <b>, and closing tags,
</b>
In well-formed HTML you should ALWAYS use
closing tags, although browsers many dont
require it
Well-formed HTML always nests tags
appropriatelye.g. <b><i></i></b> is correct
whereas <b><i></b></i> is incorrect
Creating a Web Page
Open a text browser
Type in your HTML text
Save the file with an .html extension
FTP the file to a directory located on a web
server
Youre done!
Test it by pointing a browser at the file
Lets try it!
Creating a web page using HTML
HTML Validation
You can test to see if your HTML conforms
exactly to the HTML 4.0 specification
Somewhere in the body of your page
include the following code:
<p>
<a href="http://validator.w3.org/check/referer">
<img border="0" src="http://www.w3.org/Icons/valid-html401"
alt="Valid HTML 4.01!" height="31" width="88"></a>
