Support will be added for the CSS prefers-reduced-motion media query. The prefers-reduced-motion media query detects whether the user has requested that the system minimize the amount of motion it uses; in particular motion-based animation. This is for users who either require or prefer minimized motion. For example people with vestibular disorders often desire animation motion to be kept to a minimum.
