Regardless of whether we think authors "shouldn't" use elements for
styling, it's occasionally necessary in real web sites.  No reason to
pretend it doesn't exist or complicate the example trying to hack
around the need.

That said, the *proper* treatment of that example would use Grid
Layout instead.  Then you could achieve even more arbitrary layouts
with ease.

There is no way to manually break a flex line yet - we punted that to level 2.
