Adhering to WCAG Level AA success criteria is crucial for web accessibility. Audio that plays automatically for over three seconds must provide control mechanisms to adjust volume or pause, especially for users relying on screen readers. Content that moves, blinks, or scrolls for longer than five seconds must also have pause functions unless deemed essential. This consideration is particularly beneficial for users with ADHD or dyslexia, who may struggle to focus with distracting elements. Best practices suggest eliminating autoplay and ensuring automatic content can be stopped by users.
Any audio that automatically plays for more than 3 seconds must include a mechanism to pause or control the audio's volume without affecting system volume.
Content that automatically moves, blinks, or scrolls for more than 5 seconds must include a way to pause it, except for essential content.
