That depends on how flexible this needs to be. Using a value instead
of an input method will make this feature more complicated for browser
developers and web developers. But I wouldn't mind, as long as there
are some predefined keywords for different input devices. Example:
"pointer-precision: touch", where touch could be specified to 8mm.
Shouldn't <len> rather be specified in a physical unit (in, cm, mm, pt
or pc)? A value in px might vary depending on the resolution for the
device, and em/ch depend on the font in use.
Example:
@media screen and (pointer-precision: 10mm) {
a { padding: 3mm; }
ul.autocomplete li { padding: 3mm; }
div.touchController { display: block; }
div.nonTouchController { display: none; }
}
