CSS Loader Generator
Free CSS loader generator: ten pure-CSS loading spinners with live size, speed, thickness and color controls, then copy ready-to-paste HTML and CSS code.
What does the CSS Loader Generator create?
It builds animated loading indicators in pure CSS: spinner, dots, bars, ripple, pulse, orbit, flip, wave, bounce and gradient ring. Each one is generated with your chosen size, speed, thickness and color, ready to copy as HTML plus CSS.
Do the loaders need JavaScript or images?
No. Every loader is plain HTML elements animated with CSS keyframes. There are no images, no icon fonts, no libraries and no runtime scripts — the CSS block alone is enough.
How do I add a loader to my site?
Click a loader in the grid, then copy the HTML block into your page where the loader should appear and paste the CSS block into your stylesheet. The CSS is self-contained and includes the required @keyframes rules.
What do the four parameters change?
Size controls the width and height of every loader, Speed changes the animation duration, Thickness affects borders and bar widths, and Color repaints every element instantly across the whole grid and the code output.
Why does my copied loader not animate?
The most common cause is copying only the class rules without the @keyframes block, or renaming the class in HTML but not in CSS. Copy both blocks as generated and keep the class names unchanged.
Are the animations performant?
Yes. All loaders animate only transform and opacity, which browsers can composite on the GPU without triggering layout or paint, so they stay smooth even with several loaders on one page.
Are the loaders accessible?
Spinners are visual decoration, so screen readers benefit from a text hint. Add a visually hidden label like "Loading" near the loader, or apply aria-hidden="true" to the loader and announce progress separately.
Is anything uploaded to a server?
No. The generator runs entirely in your browser. Your settings never leave the page, and the generated code is assembled locally on your device.
How to Use CSS Loader Generator
The CSS Loader Generator builds animated loading spinners in pure CSS — no images, no JavaScript, no dependencies. Pick one of ten styles, tune size, speed, thickness and color, then copy the generated HTML and CSS straight into your project.
- Adjust the global parameters with the four controls: Size sets the box of every loader, Speed changes the animation duration, Thickness controls borders and bar widths, and Color paints every element.
- Browse the grid: all ten loaders stay live-animated with your current settings so you can compare them at a glance. Click any loader to select it.
- The detail panel shows the selected loader bigger, together with its HTML snippet and the matching CSS (including the @keyframes it needs).
- Press Copy HTML or Copy CSS to send each block to your clipboard. The CSS is self-contained — paste it into your stylesheet and drop the HTML wherever the loader should appear.
- Change any parameter and the grid, the detail preview and both code blocks update instantly.
Because the loaders are pure CSS they cost almost no bandwidth and stay sharp on any display. Pair the animation with a text label for accessibility, and avoid durations below roughly 0.5s — spinners that flash too fast feel more alarming than reassuring.
