Open Props @custom-media Recipes

The @custom-media at-rule has landed in Firefox Nightly! I couldn’t find it in the release notes but Adam Argyle’s on the beat noting that it’s behind a flag for now.

Look for layout.css.custom-media.enabled

I often forget the exact name of an @media query or simply get tired writing something like @media screen and (prefers-reduced-motion: no-preference) over and over again. @custom-media will be a nice bit of relief to the ol’ muscle memory because it allows us to create aliases for queries.

In fact, Adam’s Open Props project has more than 45 of them that make for excellent recipes:

@custom-media --motionOK (prefers-reduced-motion: no-preference);

@media (--motionOK) {
  /* animations and transitions */
}
