Accessible Web Animation: The WCAG on Animation Explained

• Val Head gives a detailed overview of WCAG animation recommendations. These include:
  • “Pause, Stop, Hide“: provide a way of pausing, stopping or hiding any autoplaying animation that lasts more than 5 seconds.
  • “Three flashes or below threshold“: avoid flashing more than 3 times in a one second period, to reduce chances of triggering seizures.
  • “Animation from interactions“: any animation triggered by the user, which gives the illusion of motion (so not including things like colour or opacity change) should have an option to be disabled, as they can cause people with motion sensitivities to become ill. You can implement this with a ‘toggle’ on your site, and also pay attention to the prefers-reduced-motion media query.
• These recommendations come under different WCAG conformance levels. for example, the first two rules are level A rules – the bare minimum standard to be met. The “animation from interactions” rule is AAA, which is the highest level of conformance. In general most people aim for the middle level: AA compliance.
