Usage notes

This element implements the {{domxref("SVGAnimateElement")}}  interface.

Accessibility concerns

Blinking and flashing animation can be problematic for people with cognitive concerns such as Attention Deficit Hyperactivity Disorder (ADHD). Additionally, certain kinds of motion can be a trigger for Vestibular disorders, epilepsy, and migraine and Scotopic sensitivity.

Consider providing a mechanism for pausing or disabling animation, as well as using the Reduced Motion Media Query or equivalent User Agent client hint {{HTTPHeader("Sec-CH-Prefers-Reduced-Motion")}}  to create a complimentary experience for users who have expressed a preference for no animated experiences.
