Description

https://drafts.csswg.org/cssom-view/#the-screen-interface

availWidth and availHeight are in the spec, but not availLeft or availTop.

Those two attributes are in Chromium, Gecko and WebKit, but not EdgeHTML.

Use counters: https://www.chromestatus.com/metrics/feature/timeline/popularity/786 https://www.chromestatus.com/metrics/feature/timeline/popularity/787

There are 24,256 hits in httparchive for 'screen.availLeft', enough that I didn't try looking at how they're used.
