Flashing Animations and Parallax
Animations with flickers or movement can trigger epileptic seizures.
Best Practices
Try not to use:
- Flashing graphics or animations (i.e. something that flashes more than three times in any one second period).
- Parallax (scroll jacking).
To reduce the risk of seizures:
- Keep motion animations to an absolute minimum.
- Reduce contrast for any flashing content.
- Avoid fully saturated reds for any flashing content.
- Provide a mechanism to suppress rapid flashes.
