As a result, element remains hovered after click (has grey background in default theme).
Use @media (hover:none) to remove background if
user's primary input mechanism can't hover over elements.
See: https://developer.mozilla.org/en-US/docs/Web/CSS/@media/hover
Note 1: not all browsers support this media query
(see https://caniuse.com/#feat=css-media-interaction).
If browser doesn't support it, then the whole content of @media .. is ignored.
This is why the default behavior is placed outside of @media.
