What are microinteractions and do they improve websites?

Microinteractions are small, subtle animations that provide feedback - buttons changing colour on hover, loading indicators, form validation messages, or pull-to-refresh animations. They make websites feel responsive and polished. Good microinteractions are almost invisible but significantly improve user experience by confirming actions and reducing uncertainty. Examples include: like buttons animating when clicked, progress indicators for multi-step forms, or success animations after form submission. We implement microinteractions strategically throughout websites. They should enhance, not distract. Excessive animation actually hurts usability. We balance delight with performance - all microinteractions are optimised to avoid slowing websites. These details differentiate professional websites from amateur ones.
