Great to hear!

Indeed, the title is a bit scary. However, presentation can also be
"paged" on screen, so this is also within scope of the draft.

[Adding css3-regions & css3-multicol to subject line]

It's an interesting discussions, one I think we should have: which
advanced layout model works best for our various use cases, and for
which definition of "best".

Personally, after having worked on multicol layout for years, I think
it addresses many common use cases when combined with 'overflow:
paged' and 'column-span: <integer>'. 


The code is minimal, reusable, and pages are responsive. 

What it doesn't do -- which regions do -- is to offer positioning of
the various boxes; columns are laid out automatically, while regions
are placed manually. I have hopes that we can agree on a model with
the automation that css3-multicol provides, and with the
configurability that css3-regions offers. Here's my attempt at
resolving these:


This way we would also avoid using empty elements as dummy containers
for regions, something which I'm very opposed to. (CSS was created to
save us from tag abuse, not to add to it.)

Wow. Clever. In a weird-code kind of way :) 

The use case is the same, so I guess we have full agreement on that.
