Hi Greg and thank you for your answer. The links you provided are great.
However, I am looking for a bit more technical resources that can help me
understand why exactly the proposed solution of element queries is
infeasible to implement. Sorry, I should have been more clear about this.

>From what I get of this mail conversation it is agreed that a special
viewport HTML element needs to exist, for rendering engines to be able to
know about the separate viewport before doing the layout pass. Also,
element queries should be limited to nearest viewport ancestors, in order
to be able to layout the subtrees that the viewports create in parallel. So
the only problem left is that selectors can depend on layout.

Boris Zbarsky kinda ends the conversation with:

unsurmountable given the basic concept.

> I think it's fine as long as the UA can tell where viewport boundaries
are without doing anything related to selectors.  Again, that's where we
are with iframes.

Does that mean that this is a feasible thing to implement? I know Tab is
working with coming up with use cases for element queries but is there
anyone else pushing this forward?

Thanks
