10 principles for smooth web animations


  1. Don’t change any properties besides opacity or transform!
  2. Hide content in plain sight with opacity: 0; and pointer-events: none;
  3. Don’t animate everything at the same time
  4. Slightly increasing transition delays makes it easy to choreograph motion
  5. Use a global multiplier to design in slow motion (and then speed everything up later)
  6. Take videos of your UI and replay them to get a valuable third-person perspective
  7. Network activity can cause lag
  8. Don’t bind directly to scroll
  9. Test on mobile early, and often
  10. Test frequently on multiple devices
