RE: FN-FORUM help with divs

date posted 26th September 2002 18:54

Ah! I see where I was getting confused. I always put the absolute positioned
divs at the end of the document so their positions were absolute to the
whole page not it's container. Old bad habits die hard I guess. So absolutes
are relative and so are relatives, but I see the difference now. Maybe I
should find things out for myself and not listen to other people ALL the
time :)

Cheers!

Mike

There shouldn't be any reason why you couldn't use absolutely positioned
divs. Absolute positioning is relative to the containing box, not the
entire document. AP also has the advantage of removing the element from
the document flow (what you want in this case).

The definition of absolute [1]:
absolute
The box's position (and possibly size) is specified with the 'left',
'right', 'top', and 'bottom' properties. These properties specify
offsets with respect to the box's containing block. Absolutely
positioned boxes are taken out of the normal flow. This means they have
no impact on the layout of later siblings. Also, though absolutely
positioned boxes have margins, they do not collapse with any other
margins.
