Shimmer Text

A diagonal band of light sweeps across the element from one side to the other on hover.

Add a "Shine Sweep" hover effect (also called sheen, shiny button, shine on hover, glint, shimmer or shimmer button) to [where].
A soft diagonal band of light should sweep across the element from left to right, repeating with a short pause while the pointer stays over it.
Keep the band clipped inside the element, stop it when the pointer leaves, and don't run it for users who prefer reduced motion.

Text filled with a gradient whose colours continuously shift or flow.

Add an "Animated Gradient Text" effect (also called aurora text or a rainbow text sweep) to [where].
The letters should be filled with a gradient whose colors flow slowly and smoothly across the text in an endless, seamless loop.
Keep the text readable against its background at every moment, and hold the colors still for users who prefer reduced motion.

Gray placeholder shapes show a light highlight sweeping across them.

Add a "Skeleton Shimmer" (also called a skeleton wave or shimmer effect) to [where].
A soft band of light should sweep across the gray placeholder shapes from left to right and pause briefly before the next pass: smooth and unhurried.
Match the placeholder shapes to the real layout so nothing jumps when the content loads, and show static placeholders to users who prefer reduced motion.

Text shows shifting rainbow foil reflections that move with pointer or time.

Add a "Holographic Text" hover effect (also called holographic foil text) to [where].
While the pointer is over the text, a band of foil-like colors should glide slowly and smoothly back and forth across the letters, and the text should return to its plain look when the pointer leaves.
Keep the letters readable at every point of the shimmer, and show the same effect on keyboard focus.

A heading is cut into horizontal slices that shift sideways against each other as the page scrolls.

Add a "Sliced Text" effect (also called on-scroll sliced text) to [where].
A large heading should be cut into horizontal slices that slide sideways against each other as the user scrolls, lined up into the whole word at the start.
Tie the shift directly to the scroll position so scrolling back reverses it, and keep the heading as one readable text for screen readers.

Text is set around a circle that rotates continuously.

Add "Spinning Text" (also called circular text or text on circle) to [where].
Letters should be spaced evenly around a circle that turns slowly and steadily, with no jump when the loop restarts.
Give screen readers the text once as plain text, and stop the rotation for users who prefer reduced motion.

A heading is split into characters, words or lines that animate in one after another with a small delay.

Add a "Split Text Stagger" entrance (also called letter stagger or staggered text reveal) to [where].
Split the heading into letters that rise and fade in one after another with a short delay between them, quick and smooth without bounce.
Play it once when the heading comes into view, keep it read as one word by screen readers, and show it without motion for users who prefer reduced motion.
