Why are flashing or animated features not recommended?

Flashing and animated text and objects can be distracting, and can make screen readers read parts of the slide out of order, or not read it at all.

In addition, animated text can not be read by a screen reader, and may be difficult for low vision users to read.

Flashing objects may be a public safety issue for individuals with photosensitive epilepsy. Unless there’s a compelling business need, flashing objects should be excluded. If you feel you do have a compelling business need, ensure your object flashes below 3Hz.
