Force me to use the advanced option or to wrap the two children in a centered container? I am certain this wouldn't cover many, many edge cases, but they are called edge cases for a reason.

Edit: People can complain about tables etc being the wrong approach all they like, in the end those examples are only proof that the proper way could be at least as simple for the average case.
