The prefers-reduced-motion CSS media feature is used to detect if the user has requested that the system minimize the amount of animation or motion it uses.


Indicates that the user has made no preference known to the system.
Indicates that user has notified the system that they prefer an interface that minimizes the amount of movement or animation, preferably to the point where all non-essential movement is removed.

User Preferences

For Firefox, the reduce request is honoured if:

  • In GTK/GNOME: GNOME Tweaks > General tab (or Appearance, depending on version) > Animations is turned off.
  • In Windows 10: Settings > Ease of Access > Display > Show animations in Windows.
  • In Windows 7: Control Panel > Ease of Access > Make the computer easier to see > Turn off all unnecessary animations (when possible).
  • In macOS: System Preferences > Accessibility > Display > Reduce motion.
  • In iOS: Settings > General > Accessibility > Reduce Motion.
  • In Android 9+: Settings > Accessibility > Remove animations.
  • In about:config: Add a number preference called ui.prefersReducedMotion and set its value to 1. Changes to this preference take effect immediately.


This example has an annoying animation unless you turn on Reduce Motion in your accessibility preferences.


<div class="animation">animated box</div>


.animation {
  animation: vibrate 0.3s linear infinite both; 

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