Smoke Rotating Text
Letter by letter, the word drifts up, swells and blurs away like smoke while the next word condenses out of a haze. Each letter carries its index and each word its slot, so one keyframe runs them all.
Also known as: smoke text effect css, evaporating text animation, dissolving word swap.

}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.
