XHTML - Extensible Hypertext Markup Language

XHTML is a better, cleaner HTML. XHTML is almost identical to the old HTML 4.01 - XHTML contains all of the elements of HTML 4.01 but has the strict syntax of XML (Extensible markup language). XML is a language designed to describe data, whereas HTML was designed to display data. XML enabled devices such as cell phones or other hand-held devices can also render XHTML.

All new browsers support XHTML

The Most Important Differences between XHTML and HTML 4.01:

XHTML elements must be properly nested
XHTML documents must be well-formed
Tag names must be in lowercase
All XHTML elements must be closed

The top of the XHTML document must include exactly this:

			
			<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        		"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
			<html xmlns="http://www.w3.org/1999/xhtml">
			<head>
