Micro-Interactions: The Tiny Details That Make Websites Feel Alive

Micro-interactions are tiny animations when users do something: button pulses, content fades in, underline slides, checkmark animates.

Five types: hover effects (lift + shadow), scroll animations (fade in + slide up), loading states (skeleton screens), form feedback (border color + checkmark), success moments (celebration animation).

Impact: time on page +50%, form completion +60%, perceived quality +50%, return visits +133%.

Libraries: Framer Motion for React, GSAP for complex, CSS Transitions for simple, Lottie for icons. Quick wins: button hover lift, link underline slide, image lazy fade, smooth scrolling. Micro-interactions separate $500 sites from $5,000 ones.
