Slide Out

The element fades away while drifting off in one direction.

Add a "Fade Out Directional" exit animation (also called fade out up or fade out down) to [where].
The element should fade away while drifting a short distance in one direction: quick, speeding up as it leaves.
Remove it from the layout only after the fade ends so neighbouring content doesn't jump early, and hide it instantly 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).

The element shrinks and slides off toward an edge while fading out.

Add a "Back Out" exit animation to [where].
The element should first shrink back slightly in place, then slide off toward an edge while fading out: a deliberate two-step exit, not a single quick fade.
Remove the element only after the animation ends so the layout doesn't jump mid-motion, and remove it instantly when the user prefers reduced motion (prefers-reduced-motion).

A header hides when scrolling down and reappears when scrolling up.

Add a "Hide on Scroll Header" (also called headroom or an auto-hide navbar) to [where].
The header should slide up out of view when the reader scrolls down and slide back in on any scroll up: quick and smooth, reacting to direction rather than distance.
Always show it at the very top of the page, ignore tiny scroll jitters, and keep it visible while something inside it has keyboard focus.

Items in a group animate one after another with a small delay, forming a wave instead of appearing all at once.

Add a "Stagger" animation (also called staggered animation or cascade) to [where].
Items should fade up one after another with a short, even delay, so the group appears as a quick wave instead of all at once.
Keep the whole sequence brief even for long lists, animate once when it scrolls into view, and skip the motion when the user prefers reduced motion (prefers-reduced-motion).

The element spins and scales up from a point while fading in.

Add a "Swirl In" entrance animation (also called swirl in forward) to [where].
The element should spin well past a full turn while growing from a single point to full size and fading in: fast at first, slowing as it settles.
Play it once on a single element rather than a whole group, and show it in place without motion when the user prefers reduced motion (prefers-reduced-motion).

Letters start widely spaced and faded, then tighten into normal spacing while appearing.

Add a "Tracking In" text animation (also called text tracking in or letter-spacing in) to [where].
The letters should start widely spaced and faint, then draw together to normal spacing while becoming fully visible: smooth, slowing down at the end.
Keep the text centered and on one line while the spacing changes so the surrounding layout doesn't shift, and show it at normal spacing when the user prefers reduced motion (prefers-reduced-motion).
