Unfortunately, it looks like it can't be done. I got the idea from an online thread that I saw where they wanted to set horizontal based on ancestor and vertical based on browser window. However, the solution does not appear to be applicable to our situation (horizontal based on browser window and vertical based on ancestor). The reason seems to be that 'auto' (part of the solution on the thread I found) is calculated differently when dealing with 'left'/'right' versus 'top'/'bottom'. For that matter, since W3 appears to not explicitly define 'auto', it can be browser dependent; meaning it may show differently on different browsers.
