Template pages for XHTML 1.0

These pages may be down loaded and used to start your web page after changing the file name. They contain the basic structure of a XHTML web page. Just add the title, add to and modify the style properties and add your body.

To use these templates: Click on the link. Then use "Source" or "Page Source" in the "View" menu to show the source file. Then save the source file. Do not use "Save as ..." in the "File" menu because many browsers will mess up the page while saving it. The same problem happens if you right click the page and save it.
