I am working with a template hosted Website, so sorry I do not have access or its hard to find every style they have assigned to the divs.
They have empty DIV's setup that you can add content to. These div's take up no space when empty. When I add content suddenly the div has a big gap under my content - so either a large bottom margin/padding suddenly appears or the div height is suddenly adjusted too high.
What style could they have assigned that would suddenly cause it to have a gap when content is added? (I can override styles, but don't know what could cause this - I see nothing in Firebug)
