Meet the UtilityGlen Loading Animation Library: a collection of 116 CSS loader designs featuring spinning circles, bouncing dots, moving bars, geometric effects, and website preloaders. Preview your favorites, customize their appearance, and copy the HTML and CSS into your project.
A CSS loading animation is a visual indicator that communicates when a webpage, application, or component is processing something. You might know these effects as CSS loaders, loading spinners, website preloaders, animated progress indicators, or loading effects.
Instead of using a GIF or video, CSS animations create motion through properties such as transforms, opacity, borders, and keyframes. This makes them useful for buttons, forms, dashboards, image galleries, API requests, and many other interfaces.
The goal isn't simply to make something spin. It's to give users clear feedback while an operation is underway, without making the interface unnecessarily distracting.
Discover, customize, preview, and implement loading animations without building every keyframe from scratch.
Explore spinners, dots, bars, geometric patterns, and creative CSS effects for different interface styles.
See each loader moving before choosing it. Open an enlarged preview to inspect the effect more closely.
Get generated markup and styling that you can adapt and integrate into your own website or application.
Adjust animation color, size, speed, and preview background to suit your website's identity.
Generate a page-loading overlay that can display an animation until the initial page load completes.
Find the loader you need by name or category instead of scrolling through every animation.
Loading indicators can be calm, playful, rhythmic, or minimal. Here's a quick look at four popular approaches.
These examples show activity rather than a real completion percentage. When your application can measure progress, a determinate progress bar provides more useful information.
Adding a CSS loader to your website doesn't have to be complicated.
Browse the animations and use search or filters to narrow down the collection.
Adjust colors, size, speed, and background until the loader fits your design.
Use the Copy Code feature to obtain the animation's HTML and CSS.
Show the loader when an operation begins and hide it when the operation finishes.
Developer tip: CSS makes the loader animate, but it doesn't know when an API request or form submission is complete. Use your application's loading state to control when the animation appears and disappears.
Choosing the right visual feedback is more important than choosing the flashiest animation.
| Website Scenario | Recommended Indicator | Why It Fits |
|---|---|---|
| Page opening | Centered spinner or preloader | Communicates activity while the page becomes ready. |
| Form submission | Compact spinner or dots | Shows that the form is processing. |
| Dashboard refresh | Skeleton or inline loader | Preserves context while new data arrives. |
| File upload | Measured progress bar | Communicates actual progress when available. |
| Chat application | Typing dots | Indicates a response is being prepared. |
| Button processing | Minimal circular spinner | Fits into a small control without clutter. |
| Creative portfolio | Geometric or branded loader | Can reinforce the site's visual identity. |
Loading animations can make waiting easier to understand, but real performance still matters. Keep your effects efficient and your loading states accurate.
Motion alone may not explain what's happening to people using assistive technology. Pair visual effects with clear, accessible status information.
aria-busy="true" when appropriate.Each loading pattern communicates something different.
| Indicator | Best Used For | What to Remember |
|---|---|---|
| CSS Spinner | Operations with unknown completion time | Indicates activity, not remaining duration. |
| Progress Bar | Measurable operations | Use real progress values when available. |
| Skeleton Screen | Loading predictable content layouts | Placeholders should resemble the upcoming content. |
| Animated Dots | Messages and small waiting states | May need explanatory text for clarity. |
Everything you need to know about CSS spinners, website preloaders, animation code, and implementation.
A CSS loading animation is a visual indicator made with CSS styles and keyframes. It communicates that a page or operation is still loading. Examples include spinning circles, bouncing dots, animated bars, and geometric effects.
Yes. You can browse the collection, customize animations, preview effects, and copy generated HTML and CSS without a paid account.
The library currently contains 116 loading animation designs, including spinners, dots, bars, shapes, and creative CSS effects.
The generated HTML and CSS are intended for integration into websites and web applications. Add the code to your project and connect the loader's visibility to your application's loading state.
The animation itself can run with CSS alone. JavaScript or framework state handling is typically used to show and hide it during a particular operation.
Yes. The library includes controls for color, size, animation speed, and preview background, so you can adjust the loader to suit your interface.
Choose an animation and use the full-page preloader option. The generated overlay is designed for initial page loading. For additional asynchronous tasks, adapt the removal behavior to your application's actual readiness state.
Modern mobile browsers support CSS animations. Choose appropriate sizes, avoid unnecessary effects, and test the final implementation on your target devices.
Simple animations using transforms and opacity are generally efficient, but complex effects or many simultaneous animations can consume additional resources. Test on real devices.
A spinner is an individual loading indicator. A preloader is usually a larger loading interface shown while a webpage or application becomes ready. A preloader may contain a spinner, progress bar, text, or branded animation.
Yes. You can adapt the generated CSS and markup for component-based applications. In React JSX, change class attributes to className and connect visibility to component state.
Loading animations aren't a direct SEO ranking shortcut. They can improve the clarity of waiting states, but search visibility also depends on useful content, crawlability, mobile usability, and actual page performance. Avoid unnecessarily hiding important content behind a preloader.
