I want to add small animations, like button hover effects, loading states, and success checkmarks, to our new app. However, I’m worried that too much movement will distract the user or make the site feel slow. What is the right balance for micro-interactions? Should they be purely aesthetic, or should they always serve a functional purpose in the user journey?

Are you using CSS animations for these, or are you looking into libraries like Lottie or Framer Motion to handle the more complex interactive states?
Less is definitely more. Focus on the "Peak-End" rule—make sure the start and end of a user's task have the most delightful, subtle feedback.
That’s a great psychological tip, Amanda. A little "congrats" animation at the end of a long checkout process can leave the user with a very positive memory of the brand.
Micro-interactions should always be "functional first." Their primary job is to provide feedback. For example, a button that subtly changes color on hover tells the user it's clickable. A "pull-to-refresh" animation gives the user something to look at while the data loads, reducing perceived latency. If an animation doesn't explain a state change or guide the user's eye, it’s probably clutter. Keep your durations short—usually between 200ms and 500ms. Anything longer feels sluggish. In a 2024 test we ran, adding a simple "success" animation after a form submission reduced double-clicks by 40% because users felt confident their action worked.
Gregory, we use a mix. For simple hovers, CSS is the most performant. But for complex brand moments, like a logo morphing into a loader, Lottie is incredible because it keeps file sizes tiny. The key is to ensure these animations don't block the main thread. If the user can't interact with the app because a 2-second animation is playing, you've failed at UX. The animation should happen in parallel with the user's action, never as a gatekeeper to the next step.
