Re: [whatwg] Media query for bandwidth ??

FTR there was a working group to provide a Network Information API [1] to
let JS handle this more easily. In trying to do that, they had a difficult
time actually getting accurate information for the API to provide. So it
was canned in order to further assess the cases specifically and other
approaches. I highly doubt if there was trouble building a JS API for this
type of thing that CSS alone can handle it in some way.

If something like this is to happen, it *needs* to happen in JS first. That
way developers have control, from a working and proven implementation there
we could find a syntax for CSS to work on top of. So for now, you're
probably best off polyfilling some JS API and using that to experiment with
to present as a solution. That way it can be more easily vetted and tested.
