Media query using a discrete type feature
If matchMedia('(hover: hover)').matches
is true, you will see a pink background behind the label, and a double border around it.
If (matchMedia('(hover: on-demand)').matches
is true, you will see a green background behind the label, and a dashed border around it.
If you do not see a background color at all, your browser doesn't yet support this feature query.
