Variable Font Weight Animation

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).

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.

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.

Letters bob up and down in sequence, creating a wave running through the word.

Add a "Wavy Text" effect (also called text wave) to [where].
The letters should bob up and down one after another so a gentle, smooth wave keeps running through the word.
Loop it seamlessly, keep it read as one word by screen readers, and stop the wave for users who prefer reduced motion.

One word in a sentence is swapped for the next word in a list with a slide, flip or fade.

Add a "Word Rotate" effect (also called rotating words or flip words) to [where].
One word in the line should slide up and out while the next word from a list slides in from below, pausing on each word before the next change.
Keep the rest of the line from jumping when the words have different widths, don't make screen readers announce every change, and stop rotating for users who prefer reduced motion.
