Put a frame at the top and the bottom of the HTML page. Make the target of the top be the header and the target of the bottom be the footer. The target is simply another HTML page on your server. The middle part of the page is the stuff that changes.

>This is what I said, I don't want to use ASP.NET. I want to create a simple HTML page but don't know how to make several HTML pages share the same header and/or footer section.
