XHTML -Making the Switch

XHTML or the Extensible Hypertext Markup Language is an extension to HTML made by the w3c. XHTML is a cleaner, neater, generally faster version of HTML. Here are some things you cannot do with XHTML: Dreamweaver, Frontpage, etc. GOODBYE!!! Never use them agian, they are cheap, they are not coding, you are NOT a webmaster just becuase you can make a frontpage website. Also remember these simple things: Tags must close in the order that they open:

Hello

is not valid where as

Hello

is. All tags must close, including line breaks (now
), horizontal rules (now ), and images (now ) The alt is NEEDED. Most imporantly a doctype is needed and a character encoding is recommended. There are three types of doctypes: Transitional: Most used, most friendly, doctype.

PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"">http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Frames -For using frames, duh

PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
"">http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">

And Strict, the mean, scrict XHTML

PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"">http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

The most common character encoding is as follows,

A full list of character encodings can be found at www.w3c.org. Also in XHTML tables for layout are a big no-no. Yet most of the time the validator lets you slide with them anyway. Use CSS for layout if you want true XHTML.
