Loading spinners are one of the most commonly copy-pasted UI patterns, and yet most projects end up importing a whole spinner library just for a single animated shape. This tool generates four common pure-CSS spinner styles — no images, no JavaScript, no dependencies.
What Is the CSS Spinner / Loader Generator?
Pick a spinner style (rotating ring, bouncing dots, pulsing circle, or equalizer bars), customize its size, color, and animation speed, and copy the ready-to-use HTML + CSS — the animation is entirely CSS @keyframes, so it works the moment you paste it in.
How to Use It
- Open the tool at /tools/css-spinner-generator.
- Choose a spinner style from the dropdown.
- Adjust size, color, and speed to match your design.
- Copy the generated HTML + CSS into your project.
Key Features
- Four distinct styles: rotating ring, bouncing dots, pulsing circle, and equalizer bars.
- Pure CSS animation, using
@keyframeswith no JavaScript dependency at all. - Fully customizable size, color, and speed, with live preview as you adjust each control.
- Namespaced class names (
wdtb-prefix) to avoid collisions with your existing CSS.
When to Use This Tool
- Adding a loading indicator to a form, button, or async data-fetch UI without pulling in a library.
- Matching a spinner’s color and speed to your existing brand/design system.
- Learning how pure-CSS loading animations work by inspecting simple, readable generated code.
