Word Rotate

Existing text is animated out and replaced with new text content.

Add a "Text Replacement" effect (also called text swap) to [where].
When the text changes, the old characters should slide up and out while the new ones slide in from below, one character after another in a quick, smooth ripple.
Keep the text box from jumping in size during the swap, and announce only the new text to screen readers.

One word blurs and blends into the next in the same spot.

Add a "Morphing Text" effect (also called text morph) to [where].
One word should blur and melt into the next in the same spot with a soft, gooey merge, then hold still for a moment before the next change.
Cycle through the words seamlessly, let screen readers read the words as plain text, and stop cycling for users who prefer reduced motion.

Letters or words rotate around an axis in 3D to show the next text on their back side.

Add a "Text 3D Flip" hover effect (also called 3D flip text reveal) to [where].
When the pointer is over the text, each letter should roll over on its horizontal axis in 3D to show a new letter on its other side, one after another in a quick, smooth sweep, and roll back when the pointer leaves.
Keep the text box the same size during the flip, and show the same effect on keyboard focus.

Each digit rolls vertically to the new value when a number changes.

Add an "Odometer" number animation (also called rolling numbers or slot-machine digits) to [where].
When the value changes, each digit should roll vertically to its new digit, always rolling forward, with a slight stagger across digits and a small settle at the end.
Keep every digit the same width so the number does not shift, and expose only the final value to screen readers.

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.

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 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.
