CSS animation longer than 5 seconds Accessibility Checkpoint


Don’t use CSS animations that run for more than 5 seconds without giving the user a way to turn them off.


Reduce the duration of the animation to less than 5 seconds (works on all devices) or use the @media (prefers-reduced-motion) media query to turn them off (works in Chrome, Firefox and Safari).

Applicable standards

Note: Section 508 Refresh (2017) checkpoints are equivalent to WCAG 2.0 level A and level AA checkpoints.
