What it means
It can add motion and display a series without giving every item a separate row. The moving treatment is secondary to the content: visitors still need time to read and a way to access essential information. A saved screenshot captures only one moment of the sequence.
Use it in practice
Keep movement restrained, respect reduced-motion preferences and provide an appropriate way to pause ongoing motion. Make essential content available without chasing it.
Watch out for
Do not use endless motion to carry a critical instruction or the only route to a destination. Avoid distracting from the main action.
