This seems like a special case that's much different than other at-rules and properties. I didn't see any obvious discussion of the issue within the spec. Same issue cropped up in webkit on device pixel ratio, where -webkit-min-device-pixel-ratio does not change. In Mozilla, it does change, upon user zoom (on the desktop). With both implementations, window.devicePixelRatio is static. Microsoft introduced the metrics into window.screen, I don't believe they support the css extension at this time. Mozilla will not introduce the metrics into the scripting environment, they've expressed that they'll only keep them accessible to trusted scripts and to the css environment. https://bugs.webkit.org/show_bug.cgi?id=51190 -Charles
