I don't think you can apply a fast and steady rule to avoid a particular positioning attribute at all times. It's sometimes smart and sometimes not, but it's definitely not intrinsically bad. Maybe it's harder for a novice to use it appropriately, but that shouldn't prevent someone with more discretion from using it.

Secondly, having this as the only thing under CSS emphasizes it more than I think we want to. Perhaps the section should be removed if we can't think of anything else.
