The prefers-reduced-motion CSS media feature is used to detect if the user has requested that the system minimize the amount of non-essential motion it uses.
Warning: An embedded example at the bottom of this page has a scaling movement that may be problematic for some readers. Readers with vestibular motion disorders may wish to enable the reduce motion feature on their device before viewing the animation.
no-preferenceIndicates that the user has made no preference known to the system.
reduceIndicates that user has notified the system that they prefer an interface that removes or replaces the types of motion-based animation that trigger discomfort for those with vestibular motion disorders.
For Firefox, the reduce request is honoured if:
gtk-enable-animations = false to the [Settings] block of the GTK 3 configuration file.about:config: Add a number preference called ui.prefersReducedMotion and set its value to either 0 for full animation or to 1 to indicate a preference for reduced motion. Changes to this preference take effect immediately.This example has a scaling animation by default. If Reduce Motion is enabled in your accessibility preferences, the animation is toned down to a simple dissolve without vestibular motion triggers.
<div class="animation">animated box</div>
.animation { animation: pulse 1s linear infinite both; } /* Tone down the animation to avoid vestibular motion triggers like scaling or panning large objects. */ @media (prefers-reduced-motion) { .animation { animation-name: dissolve; } }
