CSS Loaders
100+ pure CSS loading animations. Click any loader to copy HTML + CSS code.
What is CSS Loaders?
CSS Loaders is a gallery of over 100 pure CSS loading animations that you can preview and copy without any dependencies. Loading indicators — spinners, progress bars, dots, bars, pulses, and skeleton screens — are a fundamental part of user experience, signalling that an operation is in progress and preventing users from thinking the interface is frozen.
JavaScript-based animation libraries can add kilobytes to a bundle and introduce render-blocking scripts. Pure CSS loaders avoid both problems: they run on the browser's compositor thread, meaning they stay smooth even when the main thread is busy with heavy computations. They require no JavaScript, no images, and no external libraries — just a small snippet of HTML and CSS.
This tool gathers over a hundred distinct loader designs into a single searchable gallery. Every loader is animated live in the browser so you can judge motion quality, speed, and visual weight before committing to one. Designs range from minimal single-element spinners to multi-element sequences and skeleton-screen patterns. Each loader can be customised for colour and size where applicable. Once you have found the right loader, click Copy to get the complete HTML and CSS snippet — including the '@keyframes' block — ready to paste into your project. This tool is useful for frontend developers, UI designers, and anyone building web applications that need polished, performant loading states without the overhead of an animation library.

Frequently Asked Questions
CSS loaders are infinitely scalable, easily themed with CSS variables or custom properties, and run on the compositor thread for smooth animation. GIFs are fixed-resolution and cannot be easily recoloured. Inline SVG animations are comparable but require more markup.
Yes. Most loaders use a single CSS color value — either a named color, hex, or CSS custom property. Changing one variable is usually all it takes to rebrand a loader.
Yes. CSS animations are supported on all modern mobile browsers including Safari on iOS and Chrome on Android. Performance is generally excellent because animations run on the GPU compositor.
Yes, but be mindful of cognitive load. Each visible animation draws user attention. For most interfaces, a single loader per asynchronous region is enough to communicate progress clearly.
