HTML_DOCUMENT = <HTML to XHTML Example: HTML page
This is the HTML page. It works and is encoded just like any HTML page you
have previously done. View the XHTML version of
this page to view the difference between HTML and XHTML.
You will be glad to know that no changes need to be made to any of your CSS files.
