Micro-interactions: The Small Details That Make Interfaces Feel Alive
Micro-interactions are the small responses to user actions that make an interface feel responsive and considered. Here is how I design them. Micro-interactions are the tiny animations and feedback responses that happen when a user does something. A button that depresses on click, a toggle that slides, a form field that highlights on focus, a like button that bursts when tapped. Individually, each is trivial. Together, they are the difference between an interface that feels mechanical and one that feels alive. After designing micro-interactions for years, here is how I approach them. Feedback First, Decoration Second The primary job of a micro-interaction is feedback. When a user taps a button, they need to know the tap registered. When they submit a form, they need to know it is processing. When they toggle a setting, they need to see the new state. The animation serves this feedback. If the animation is beautiful but the feedback is unclear, the interaction has failed. I start every micro-interaction by asking what feedback the user needs. Only after the feedback is clear do I consider how to animate it. A button press needs to show the button is pressed, so it scales down slightly and changes color. More guides are on the Spark Blog.
