Which browsers already support Media Queries Level 4?

css

Solution

Here, on CanIUse, you can find updated and current support for many CSS properties. In this specific case, some of Level 4 Media are already supported even if in not standard way, such as:

- "API for finding out whether or not a media query applies to the document"

- "Method of accessing external device data (such as a webcam video stream)"

Problem

Which browsers already support some of these attributes? http://dev.w3.org/csswg/mediaqueries4/ This one f.e. does not work on iOS7, iPhone 4S ``` @media (luminosity: normal) { body { background: #f5f5f5; color: #262626; } } @media (luminosity: dim) { body { background: #e9e4e3; } } @media (luminosity: washed) { body { background: #ffffff; } } ```
