+<p>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.</p>
+
+<p>Consider providing a mechanism for pausing or disabling animation, as well as using the <a href="https://wiki.developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion">Reduced Motion Media Query</a> to create a complimentary experience for users who have expressed a preference for no animated experiences.</p>
