Not at all.
If the trivial case "three boxes 1/2 1/4 1/4 all same height whatever
the content" cannot be *intuitively* solved, and that's the very first
case *all* designers need and will try (actually "tried" if you read
Jeremie's emails), the module has a serious problem.

Yes.

Right. But "width: 0" is far from intuitive and readable and I think
the rule should be on the box, not its contents...
I just want something that users (read web authors) will understand
immediately when they read the corresponding css rules.
