Animated Gradient Text

A bright highlight sweeps repeatedly across the letters.

Add a "Shimmer Text" effect (also called animated shiny text or metallic shimmer text) to [where].
A band of light should sweep smoothly across the letters from left to right, then repeat after a short pause.
Keep the text readable under the highlight, and keep it still for 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.

Colors in a gradient background slowly shift, pan or rotate.

Add an "Animated Gradient" background (also called a gradient animation or moving gradient) to [where].
The colors of the gradient should slowly pan across the area in a soft, continuous drift, with no visible jump when the loop restarts.
Keep text on top readable against every color, and stop the movement for users who prefer reduced motion.

Big letters act as a window showing a playing video inside them.

Add a "Video Text" effect (also called text video mask) to [where].
Big, bold letters should act as a window onto a playing video, so the moving footage shows only inside the letter shapes.
Keep the video muted and looping without controls, provide the words as real text for screen readers, and show a still frame for users who prefer reduced motion.

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.

Text scales, moves, or rotates as a moving graphic element rather than static copy.

Add "Kinetic Typography" (also called kinetic text) to [where].
Rows of large repeated text should slide sideways in alternating directions at a slow, steady pace, turning the words into a moving graphic.
Make each row loop seamlessly without a visible jump, let screen readers read the text only once, and stop the motion for users who prefer reduced motion.
