Animate.css is a CSS animation library and browser-based motion framework. It provides a collection of pre-made animations and motion effects used to add visual movement to web elements across different browsers.
The library is designed as an accessibility-aware system that automatically disables animations when the operating system has a reduce motion setting enabled. This ensures that web motion respects user preferences for accessibility.
The framework covers front-end visual effects and cross-browser UI styling. It utilizes a utility-first architecture with predefined style classes to manage web element animation.
