CSS prefers-reduced-motion Media Query

By  on  

When I started in the web development industry, media queries were limited -- screen and print were the two media queries I was most often using. More than a decade later, media queries have advanced to various screen units, feature checking, and even color scheme preference. I've been so happy to see CSS evolve beyond incredibly generic settings.

One of the CSS media queries I've recently discovered is prefers-reduced-motion, a media query for users sensitive to excessive motion.

Let's use prefers-reduced-motion to show motion to all users but none to sensitive users:

.animation {
  animation: vibrate 0.2s; 
}

@media (prefers-reduced-motion: reduce) {
  .animation {
    animation: none;
  }
}

The example above illustrates how we can cater to sensitive users by not animating elements for those who have said they don't want them.

It's amazing how media queries like this can really show users that you care. Sure, we love the fancy razzle-dazzle but not everyone can handle that motion.

    Control Element Outline Position with outline-offset

    I was recently working on a project which featured tables that were keyboard navigable so obviously using cell outlining via traditional tabIndex=0 and element outlines was a big part of allowing the user navigate quickly and intelligently. Unfortunately I ran into a Firefox 3.6 bug...

    CSS Ellipsis Beginning of String

    I was incredibly happy when CSS text-overflow: ellipsis (married with fixed width and overflow: hidden was introduced to the CSS spec and browsers; the feature allowed us to stop trying to marry JavaScript width calculation with string width calculation and truncation.  CSS ellipsis was also very friendly to...

    As someone that has suffered vestibular disorders before, prefers-reduced-motion is a godsend.

    A somewhat better, broader implementation is using the a really short animation-duration instead of animation: none, as it’s fairly common to implement animations in such a way that starts off screen or otherwise invisible, which could mean the elements don’t show up at all if using animation: none. Iteration count will prevent us from getting infinite loops.

    Same thing can be achieved for transitions.

    @media screen and
      (prefers-reduced-motion: reduce){
      * {
        animation-duration: 0.001ms !important;
        animation-iteration-count: 1 !important; 
        transition-duration: 0.001ms !important;
    
      }
    }
