These guidelines help you create materials that are accessible to everyone
Planning for accessibility from the beginning will lead to more inclusive materials and is easier and less costly than remediating them later.
In addition to making your materials more inclusive, there is real risk of harm if they are not. Flashing, motion and animations can cause physical harm, ranging from dizziness and nausea to seizures and even death. So make sure you use motion, parallax, and animations thoughtfully.
