Web Animations Guide
Animations bring websites alive — when used with restraint. Learn which animations matter and how to implement them.
1. Scroll Reveal
Fade-in elements as they enter viewport using IntersectionObserver. 300ms fade with 20px translate.
2. Hover Effects
Subtle hover states: scale 1.02, shadow increase, color shift. 200ms transitions.
3. Loading States
Skeleton screens and progress bars reduce perceived load time dramatically.
4. Micro-Interactions
Button ripples, form feedback, and toggle animations reward interaction.
5. Performance
Prefer transform & opacity animations (GPU accelerated). Avoid animating width, height, or layout properties.
Key Takeaway
Animate only transform & opacity — they run on the GPU and never trigger layout
