Hinge

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 spins around a pivot while fading away.

Add a "Rotate Out" exit animation to [where].
The element should spin around its center, a little over half a turn, while fading away: smooth, speeding up as it goes.
Remove it only after the spin ends, and hide it instantly when the user prefers reduced motion (prefers-reduced-motion).

The element rolls off to the right while fading out.

Add a "Roll Out" exit animation to [where].
The element should roll off to the right like a wheel, turning as it travels, while fading out: smooth, speeding up as it leaves.
Remove it from the layout only after it has rolled away, and hide it instantly when the user prefers reduced motion (prefers-reduced-motion).

The element pops up from a small rotated state, overshoots, and settles like a jack-in-the-box toy.

Add a "Jack In The Box" entrance animation to [where].
The element should pop up from a tiny, tilted state anchored at its bottom edge, rock from side to side past upright, and settle: springy and playful.
Play it once only, and show the element in place without motion when the user prefers reduced motion (prefers-reduced-motion).

The element shoots in from the side with a skew that straightens as it lands.

Add a "Light Speed In" entrance animation (also called lightspeed in) to [where].
The element should shoot in fast from the side, slanted as if moving at speed, then overcorrect the slant once and straighten as it lands: fast and dramatic, slowing at the end.
Keep it from causing a horizontal scrollbar while it is still off-screen, and show it in place without motion when the user prefers reduced motion (prefers-reduced-motion).

The element skews and speeds off to the side while fading.

Add a "Light Speed Out" exit animation (also called lightspeed out) to [where].
The element should slant and speed off to the side while fading out: fast, accelerating as it leaves.
Keep it from causing a horizontal scrollbar as it passes the edge, and hide it instantly when the user prefers reduced motion (prefers-reduced-motion).
