Go Organic with Border Radius Generator

The **Border Radius Generator** goes far beyond simple rounded corners. Did you know CSS allows up to eight values for `border-radius`? This enables the creation of organic, non-uniform shapes often called "blobs" that are popular in modern, friendly web design.

The 8-Value Syntax Explained

Standard syntax (e.g. `10px`) creates symmetrical corners. However, using the slash syntax (e.g., `60% 40% / 50% 50%`), you can define horizontal and vertical radii independently for each of the four corners. This tool visualizes these complex handles, allowing you to drag and morph a box into a lemon, an egg, or a random organic background shape.

Why use organic shapes?

Perfect squares and circles can feel rigid and corporate. Organic shapes feel:

  • Friendly & Approachable: Human-centric design often avoids sharp edges.
  • Dynamic: Asymmetrical shapes guide the eye and break the grid layout monotony.
  • Unique: Stand out from standard Bootstrap-style templates.

How to Use

  1. Drag the 8 handles around the square.
  2. Watch the shape morph in real-time.
  3. Create a 'Blob' for use as an avatar background.
  4. Copy the complex `border-radius` syntax string.

Technical & Privacy Note
