Can these be used together on the same page? I am currently using php includes to scroll external html pages with css formatting - h1;h2's etc.
The user does not scroll the main page and lose sight of images and the footer. I do not want the visitor to lose sight of the footer. I would like to compare user acceptance of the 2 methods.

Also what about sticky footer, sticky header and dynamic page working together?

PS. SE's definitely read the content of php includes whereas they do not read i-frame information.
PPS. I am using h1's etc for ease of change mostly although the jury is out on search engine usage.
