Puff In / Puff Out

The element starts heavily blurred and sharpens into focus, often while sliding or fading in.

Add a "Blur In" entrance animation (also called text focus in, focus in or blur text reveal) to [where].
The content should start heavily blurred and transparent, then sharpen into focus in place: soft and fairly slow, with no movement.
Play it once, and show the text sharp right away when the user prefers reduced motion (prefers-reduced-motion).

The element shrinks and fades until it vanishes.

Add a "Zoom Out" exit animation (also called scale out) to [where].
The element should shrink toward its center while fading until it vanishes: quick, speeding up as it goes.
Remove it from the layout and from keyboard focus only after it has vanished, and hide it instantly when the user prefers reduced motion (prefers-reduced-motion).

The element blurs progressively while fading or sliding away.

Add a "Blur Out" exit animation (also called text blur out or smoky text dissipate) to [where].
The content should grow more and more blurred while fading away in place: soft and fairly slow, as if it dissolves.
Hide or remove the element only after the blur finishes, and hide it instantly when the user prefers reduced motion (prefers-reduced-motion).

The element grows from a small, transparent state to full size while fading in.

Add a "Zoom In" entrance animation (also called scale in) to [where].
The element should grow from small and transparent to full size while fading in: quick and smooth, with no overshoot.
Scale it from its center without affecting the surrounding layout, and show it in place without motion when the user prefers reduced motion (prefers-reduced-motion).

The element rolls in from the left like a wheel while fading in.

Add a "Roll In" entrance animation to [where].
The element should roll in from the left like a wheel, turning as it travels, while fading in: smooth, slowing down as it lands.
Play it once, and show the element in place without motion 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 spins in around a corner or its center while fading in.

Add a "Rotate In" entrance animation (also called rotate in down left) to [where].
The element should swing into place around its bottom-left corner from a tilted angle while fading in: smooth and unhurried, easing out as it settles.
Play it once, and show the element in place without motion when the user prefers reduced motion (prefers-reduced-motion).
