Hover text where every letter rolls out of view and is replaced by a copy rolling in, staggered from first to last for a crisp mechanical rhythm.
Letter Swap turns a short label into a small piece of kinetic type. On hover or keyboard focus, each character slides down out of its clipped slot while an identical character slides in from above, one after another with a 30 millisecond stagger and a springy settle. The full label stays available to screen readers as a single string, the decorative letters are hidden from assistive technology, and the animation is disabled for visitors who prefer reduced motion. It suits navigation links, footer menus, oversized headings and buttons where you want text to feel tactile without changing its layout or size.
