Subtle animations do more than look good—they guide users, create hierarchy, and make interfaces feel alive. The right motion can clarify relationships between elements and signal what's interactive.
But motion for motion's sake is noise. Every animation should serve a purpose: to orient, to focus, or to delight. The best motion design goes unnoticed until it's gone.
Respect reduced-motion preferences. Accessibility isn't optional—it's fundamental to inclusive design.
