Position element before its previous sibling

HTML & CSS

I have a right column 250px wide and in this column I have two divs, each 250px wide but of variable height. What I would like to do is position the second div before (above) the first div. Is this possible using CSS?

Using fluid heights the short and simple answer is no.

We are able to use relative positioning to shift fixed width columns around on the x-axis but that approach will not work with fluid heights on the y-axis.

Thanks, I thought that was probably the case.
