Falling Letters Rotating Text
Letter by letter, the old word tumbles out of the headline and the next one drops in from above with a small bounce. Every letter carries its index, and every word its slot, in custom properties.
Also known as: letter by letter word swap, letters drop text rotator, per letter word change.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
