.. how to disable hover states on elements for touch screens.

The problem: “If you tap on something that has a :hover state but you don’t leave the page then, on a mobile device, there is a chance that :hover state “sticks.”

You can solve this by using the CSS4 media query @media (hover: hover)

In my case, the complete code looks like this:

@media (hover: hover) and (pointer: fine) {
  &:hover .filters__label-checkbox:after {
    border-color: $brand-primary;

This allows me to have a red border on :hover (on custom checkboxes) for desktop but removes it for touch screens.
