Motion design is the use of animation and movement in digital interfaces. Things like transitions, micro-interactions, loading states, and hover effects.

Done well, it makes a product feel more polished and alive, but its real value is functional: motion guides attention, communicates cause and effect, and helps users understand what just happened or what to do next.

A button that bounces when clicked, a menu that slides in from the side, or a form field that shakes on error — these aren't just decorative, they reduce cognitive load and make interfaces feel more intuitive. The key is restraint; good motion design is usually the kind users don't consciously notice.
