- Avoid causing the screen to flicker; large flickering or flashing images may cause seizures in users with photosensitive epilepsy. These seizures can be triggered by flickering or flashing in the 4 to 59 flashes per second (Hertz) range, with greatest sensitivity occurring at 20 flashes per second. Rapid tonal changes can have the same effect.
- Provide clear text alternatives for continuous animation.
- Check accessibility by viewing your page in multiple browsers and platforms, then verify it with tools like CAST's on-line BOBBY verification tool.
