Shake

The element wobbles side to side with slight rotation like a head shaking no.

Add a "Head Shake" attention effect (also called headshake or no shake) to [where].
The element should turn quickly side to side with a slight twist, like a head shaking no, each turn smaller than the last before it settles.
Play it once each time it is triggered, such as on a rejected action, and keep the surrounding layout from moving.

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 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 stretches horizontally and squashes vertically in elastic steps before returning to normal.

Add a "Rubber Band" attention effect (also called rubberband) to [where].
The element should stretch wide and squash short, then spring back through a few smaller elastic steps before settling at its normal size.
Play it once when triggered, and keep the surrounding layout from shifting while it stretches.

The element rotates continuously at constant speed.

Add a "Spin" effect (also called a spinner or rotate loop) to [where].
The element should rotate continuously at a constant, even speed, with no easing between turns.
Make the loop seamless, give the spinner an accessible loading label, and slow or stop it for users who prefer reduced motion.

The element swings back and forth from its top edge like a pendulum with decaying amplitude.

Add a "Swing" attention effect to [where].
The element should swing back and forth like a hanging sign, starting with a wide swing that quickly dies down.
Pivot it from its top edge rather than its center, and play it once when triggered.

The element scales up, wiggles with rotation, and returns to size in a celebratory flourish.

Add a "Tada" attention effect to [where].
The element should dip slightly smaller, then grow and wiggle side to side with a quick tilt before returning to its normal size, like a small celebration.
Play it once, for example right after a success, and skip it for users who prefer reduced motion.
