Uses only transform and opacity for animations, ensuring smooth performance without JavaScript overhead, as emphasized in the README for lightweight loading.
Each spinner is self-contained with no shared classes or animations, making it easy to extract and use only needed code, reducing bloat.
Configurable via --sk-size and --sk-color variables for quick size and color changes, with direct style overrides possible for finer control.
Includes the sk-center class that sets margin to auto, simplifying alignment without additional CSS for common use cases.
Offers 12 distinct spinner types like Plane, Chase, and Wave, providing visual diversity to match different UI designs.
Relies on CSS animations and variables with less than 100% global support, requiring manual fallback code for older browsers, as noted in the README.
No component system or package manager automation; users must copy-paste CSS and HTML snippets, which can be error-prone in larger projects.
Only provides indeterminate loading indicators, lacking features like progress bars, percentage displays, or advanced animation controls.
Beyond CSS variables, modifying animations or styles requires understanding of CSS keyframes and properties, which may be a barrier for beginners.
