Sliced Text

Text jitters with sliced offsets and red/cyan colour splits like a broken signal.

Add a "Glitch Text" hover effect (also called text glitch or RGB split glitch) to [where].
While the pointer is over the text, it should jitter in quick, snappy bursts: thin horizontal slices jump sideways and two colored copies split apart like a broken signal, then settle back when the pointer leaves.
Keep the real text in the document only once so screen readers don't read the copies, and show the same effect on keyboard focus.

Large text lines slide horizontally as the page is scrolled vertically.

Add a "Text Marquee on Scroll" (also called a scroll text marquee or scroll velocity text) to [where].
Large lines of text should slide sideways as the page scrolls down, with alternate rows moving in opposite directions, and slide back when scrolling up.
Tie the movement to the scroll position, keep the long lines from causing a horizontal scrollbar, and keep them still for users who prefer reduced motion.

Letters of a title shuffle or move sequentially as the user scrolls through sections.

Add "Scrolling Letters" (also called on-scroll letter animations) to [where].
As the user scrolls through the sections, the letters of the title should roll to their next characters one after another from left to right, tied directly to the scroll position.
Scrolling back up should roll them back, and screen readers should get the current title as plain text.

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.

Characters flip like an airport departure board until they land on the target letter.

Add a "Split-Flap Text" effect (also called a text flipping board or flip board) to [where].
Each character tile should flip quickly through the alphabet until it lands on its target letter, with the tiles settling one after another from left to right.
Run it once each time the text appears or changes, announce only the final text to screen readers, and show the final text without flipping for users who prefer reduced motion.
