Microinteractions are subtle animations designed to offer visual feedback or signal a state change in the user interface. These elements typically involve a trigger, which can be initiated by users or the system, and a corresponding feedback mechanism.

While microinteractions play a crucial role in enhancing user experience by making interactions feel intuitive and satisfying, it's important to use them judiciously. Overuse can lead to visual clutter and detract from the overall user experience. Additionally, designers should consider accessibility when implementing microinteractions, ensuring they don't alienate or confuse users with varying abilities.
