Right. I don't know where I've got it from but thanks for the info.
Since the topic name is still relevant I'd like to ask another question about the same subject.
I need to place a menu div like "halfway" over the content div. As soon as I use position relative or absolute the div moves to the top left corner.
Since I need the div to be in a position based on the content div, is there a way to do this properly? I guess if I position the div correctly on my screen it will not be on the same position on a computer where they use another resolution? True or false?
