Device media queriesLimited availability
The device-aspect-ratio, device-height, and device-width media features describe physical properties of the displaying output device.
Not yet supported in all major browsers — check the table and provide a fallback.
Discouraged: Device media queries do not reflect available layout, only the physical size of the device. Use instead: Media queries
