> A CSS Loader Generator builds a pure-CSS loading spinner — ring, dual ring, dots, bars, or pulse — from a single HTML element, outputting the rule and @keyframes ready to paste.

Choose a loader style and tune size, thickness, color, and speed; the preview is rendered from the exact CSS you copy, keyframes included. Every loader is deliberately a single element with no wrapper divs or extra spans, so it drops into any markup — including onto a pseudo-element — without touching your component structure. No JavaScript, no GIFs, no requests.

## Features

- Five styles: ring, dual ring, dots, bars, pulse
- Single-element markup — no wrapper divs
- Size, thickness, color, track, and speed controls
- Outputs the rule plus its @keyframes
- Preview rendered from the generated CSS itself
- No JavaScript and no image requests

## Use cases

- Showing a spinner while data loads
- Adding a loading state to a button
- Placeholder animation for a skeleton screen
- Replacing a loading GIF with pure CSS

## How to use it

1. **Pick a style** — Choose ring, dual ring, dots, bars, or pulse.
2. **Tune it** — Set size, thickness, color, and speed.
3. **Copy the CSS** — Copy the rule and keyframes into your stylesheet.

## When to use it, and when to use something else

- **vs A loading GIF or animated SVG** — use CSS Loader Generator when you want no extra request, crisp scaling, and recoloring from CSS. Use A loading GIF or animated SVG when you need illustrated or branded animation.
- **vs A spinner from a UI library** — use CSS Loader Generator when you don't want a dependency for one animation. Use A spinner from a UI library when you're already using that library's components.

## Frequently asked questions

### Do these loaders need JavaScript?

No. Each one is a CSS rule plus @keyframes on a single element — no scripts and no image requests.

### Why single-element loaders?

Because they paste in anywhere, including onto a ::before or ::after pseudo-element, without changing your markup or component structure.

### Should a loader respect prefers-reduced-motion?

For decorative motion, yes. A loader's animation communicates state, so most teams keep it and simply slow it down — wrap the animation in a prefers-reduced-motion media query if you want to be strict.

### How do I make the loader accessible?

Give the element role="status" and an aria-label, or pair it with visually hidden text, so screen readers announce that content is loading.
