Frequently Asked Questions

Pure CSS loaders are lighter, require no JavaScript, and don't block the main thread. They work even if JS fails to load, making them ideal for initial page loading states. JS loaders (like Lottie animations) offer more complex animation possibilities but add file size and a JS dependency. For simple spinners, always prefer CSS.

Add role="status" and aria-label="Loading..." to the loader element so screen readers announce it. Respect the prefers-reduced-motion media query to stop or slow animations for users who have opted out. Use @media (prefers-reduced-motion: reduce) { .loader { animation: none; } } to disable animations when requested.

CSS animations using transform and opacity are GPU-accelerated and generally very performant since they avoid layout and paint. Avoid animating properties like width, height, top, left, or margin, which trigger reflow. The loaders in this tool only animate transform and opacity to ensure smooth 60fps performance.
