On this page

    Videos or animations on a page risk causing seizures in people with Photosensitive Epilepsy.

    Be conscious of the fact that animation does not need to be produced by an animation application such as Photoshop or Flash. Using JavaScript to change the color of a <div> rapidly or through certain color ranges (especially if it’s a large <div>) can cause issues.

    If you have access to a Windows computer, check the video or animated assets using the Trace Research & Development Center’s free Photosensitive Epilepsy Analysis Tool (PEAT) to identify risky material.
