SpinKit is a UI component library and CSS animation library focused on providing a collection of animated loading indicators and spinners. It serves as a set of lightweight visual transitions designed to create motion and feedback within web interfaces.
The library implements these indicators using pure CSS rendering and keyframe animations to notify users of active background processes. It uses a class-based styling system and minimal HTML structures to render visual cues without relying on scripts or images.
Appearance can be adjusted through CSS variables and custom styles to modify colors and dimensions. This allows the loading indicators to be customized to match specific brand palettes and interface layouts.
