I was seeing a way to determine if user access is done by a Desktop, usually by having a mouse as the interaction device. Or if the user is accessing a mobile device, usually without the mouse to interact with the screen.
Then I saw that it is possible to treat this with the rules
@media (pointer: X) or
@media (any-pointer: X) where in
pointer: X you define whether or not there is a mouse .
X can be:
none: No pointing device is available.
coarse: At least one input mechanism includes a precision precision pointing device.
fine: At least one input mechanism includes an accurate pointing device.
The problem is that for both% and% with% values are equal and represent the same thing, so what is the difference between one and the other?
