I agree with your post, but I think you only address half of the issue: the other half is the incorrect coupling. In terms of maintainability it does not make sense to have a bunch of random things with a class of "narrow" because then you can't predictably change the "narrow" class. It's really hard though, and I don't see a clear answer using CSS without some kind of OO addon (less, sass etc.)
