Border Radius Generator

Mastering Border Radius

The CSS border-radius property allows you to round the corners of an element's outer border edge. While most people use a single value (like border-radius: 8px), the property is incredibly powerful and can be used to create complex, organic shapes.

Simple vs. Advanced Syntax

Simple (4 values): Defines the radius for the top-left, top-right, bottom-right, and bottom-left corners respectively.

Advanced (8 values): You can specify independent horizontal and vertical radii for each corner by using a slash (/). This allows you to create elliptical corners rather than purely circular ones, resulting in organic "blob" shapes.

Organic Shapes (Blobs)

By carefully balancing the 8 values using percentages, you can create smooth, continuous curves that look like natural, organic blobs. These are excellent for modern, playful backgrounds, profile picture masks, or creative UI elements.
