The element rocks side to side with tilt like a wobbly object.

Add a "Wobble" attention effect to [where].
The element should rock side to side with a tilt, starting with a big sway that shrinks with each swing until it settles.
Play it once when triggered, and keep neighbouring content from shifting.

The element scales in a double-beat rhythm like a beating heart.

Add a "Heartbeat" effect (also called heart beat) to [where].
The element should swell and relax in a quick double beat, then rest briefly before the next beat, like a beating heart.
Loop it seamlessly with the rest kept between beats, and stop it for users who prefer reduced motion.

The element skews back and forth with decaying amplitude like a wobbling jelly.

Add a "Jello" attention effect (also called jelly) to [where].
The element should skew back and forth like a wobbling jelly, strong at first and quickly settling to rest.
Play it once when triggered, and keep the element's footprint so nearby content does not shift.

The element jitters quickly back and forth along one axis.

Add a "Shake" effect (also called an error shake or invalid input shake) to [where].
The element should jitter quickly left and right a few times and stop exactly where it started: fast and firm.
Play it once each time the error happens rather than looping, and pair it with a visible error message so the meaning does not rely on motion alone.

The element trembles rapidly in tiny multi-directional jolts, like a phone vibrating.

Add a "Vibrate" attention effect (also called buzz or vibration) to [where].
The element should tremble in tiny, rapid jolts in different directions for a brief moment, like a phone buzzing, then settle.
Keep the movement very small so the content stays readable, and play it once per alert instead of looping.

The element hops up and down with decelerating bounces.

Add a "Bounce" attention effect to [where].
The element should hop up and drop back down in a few quick bounces that get smaller each time, with a slight squash as it lands.
Play it once when triggered rather than looping, and skip it for users who prefer reduced motion.
