Observation Details
All animated content (layered "sketch" images, smartphone "carousel") has not mechanism to pause, stop, hide.
Remediation Notes
Ensure to provide a mechanism to pause, stop, hide for all moving objects / animations that automatically start and last longer than 5 seconds.
Also ensure to respect user preferences like prefers-reduced-motion, and reduce animation. You can use a media query as follows to wrap all animation to ensure animations are only shown to users that want to see them. (Side note: this is not a stand-alone remediation for the issue; it is an additional step. The pause, stop, hide mechanism must exist anyways)
