Fancy Border Radius is a free visual CSS generator for creating organic blob-like shapes using only the CSS `border-radius` property — no SVG needed. Get copy-paste CSS code instantly.

## What is Fancy Border Radius?

[Fancy Border Radius](https://9elements.github.io/fancy-border-radius/) is a free, browser-based tool by 9elements that lets you visually create complex, organic shapes using CSS's `border-radius` property.

Most people know `border-radius` for making rounded corners (`border-radius: 8px`), but CSS actually supports a much more powerful 8-value syntax:

```css
border-radius: 40% 60% 70% 30% / 40% 50% 60% 50%;
```

This creates completely asymmetric, blob-like organic shapes — and Fancy Border Radius gives you a visual editor to build them without writing a single line of CSS manually.

## Why Use Fancy Border Radius Instead of SVG Blobs?

Unlike [Blob Maker](/resources/blob-maker/) which generates SVG shapes, Fancy Border Radius generates **pure CSS** — which means:

- ✅ **Smaller file size** — No SVG markup, just a CSS property
- ✅ **Infinitely scalable** — CSS shapes scale perfectly at any resolution
- ✅ **Animatable** — CSS `border-radius` can be smoothly animated with `transition` or `@keyframes`
- ✅ **Reusable** — Apply to any element with a class, works on images, divs, buttons, and more
- ✅ **No JavaScript** — Pure CSS, no dependencies

## How to Use It

1. Go to [9elements.github.io/fancy-border-radius](https://9elements.github.io/fancy-border-radius/)
2. Drag the 8 control points around the preview shape
3. Watch the shape update in real-time as you drag
4. Copy the generated CSS value
5. Apply it to any element in your stylesheet:

```css
.blob-shape {
  border-radius: 40% 60% 60% 40% / 60% 30% 70% 40%;
  background: #7c3aed;
  width: 300px;
  height: 300px;
}
```

## Animating Fancy Border Radius Shapes

One of the biggest advantages over SVG blobs is CSS animation support:

```css
@keyframes morph {
  0%, 100% { border-radius: 40% 60% 70% 30% / 40% 50% 60% 50%; }
  50% { border-radius: 70% 30% 40% 60% / 60% 40% 50% 40%; }
}

.animated-blob {
  animation: morph 6s ease-in-out infinite;
}
```

## Common Use Cases

- 🔵 **Background accent shapes** — Decorative blobs in brand colors
