I've got the following dilemma.
I have a 3 column CSS layout design. The page length is dynamic depending on how much content gets fed into each respective column. For this reason one column might be considerably longer than the other two, as a result the page length opens us white space in some columns.
Given the white space that appears if some content in columns is longer than in others, how could I measure the white space and depending on its height dynamically add in further content providing it fits (say additional side banners)?
I'm told this is possible in JS? I guess PHP is also a viable option?
Thanks a lot,
