Likely I haven’t correctly described my problem, since I was a bit in a hurry, so it could be understand wrongly:
Basically there is a footer bar that should be displayed on each page of a project, without getting adjusted its position manually. Therefore I’m looking for an action that places an HTML object after the last visible object within the page.
Unfortunately I could not find a solution at the thread you directed me to.
A flexible CSS layout should accomplish what you want. Have a look at thebigerns.com for instance. You don’t need to copy the three column layout: you can easily adapt this to one or two columns. The essential thing is that the footer moves in response to the content above it.
