Frequently Asked Questions
Do these loaders use JavaScript?
No! All animations are pure CSS using @keyframes. They work without any JavaScript.
Are these loaders accessible?
Yes, if you add role="status" and an aria-label to the loader element. Users who prefer reduced motion can be accommodated with a prefers-reduced-motion media query.
How It Works
- Choose a loader style: Select from spinners, dots, bars, rings, pulses, or skeleton loaders.
- Customise appearance: Adjust color, size, animation speed, and thickness using sliders.
- Preview the animation: The loader animates live in the preview area so you can see exactly how it will look.
- Copy HTML and CSS: Get the minimal HTML markup and CSS required — no JavaScript dependencies needed.
Why Use CSS Loader Generator?
Loading indicators are essential UX elements that communicate activity and prevent users from thinking the page is frozen during async operations. Pure CSS loaders — using only CSS animations without JavaScript or image files — are lightweight, reliable, and render at 60fps using GPU-accelerated transforms. This generator creates production-ready loading spinner code that you can drop directly into your project. All animations use @keyframes with transform and opacity — the two CSS properties that animate without causing layout reflow, ensuring smooth 60fps performance even on low-end devices.
Available Loader Types
- Spinner — rotating circle, the most universal loader
- Dots — three bouncing dots in sequence
- Bar / Progress — horizontal progress-style animation
- Ring — border-based ring spinner with glow
- Pulse — scaling/opacity pulse effect
- Skeleton — content placeholder shimmer for page loading
