The pointer CSS media feature tests whether the user has a pointing device (such as a mouse), and if so, how accurate the primary pointing device is.
Note: If you want to test the accuracy of any pointing device, use any-pointer instead.
Syntax

none-
The primary input mechanism does not include a pointing device.
coarse-
The primary input mechanism includes a pointing device of limited accuracy, such as a finger on a touchscreen.
fine-

Examples
