Why Use Use a Border Radius Generator?

Memorizing which value corresponds to which corner in the 4-value syntax can be confusing. This tool visualizes the changes instantly, allowing you to create complex organic shapes (like leaves or blobs) without mental math.

Frequently Asked Questions

What is the order of the 4 values?

The standard order is: `Top-Left`, `Top-Right`, `Bottom-Right`, `Bottom-Left` (clockwise starting from top-left).

Can I use percentage values?

Yes, CSS supports percentages (e.g., `50%` to make a circle). This generator outputs pixel values for precision, but you can manually change `px` to `%` in your code.

How do I make a pill shape?

Set a very high border-radius (e.g., 999px) on all corners. The browser will cap it at the maximum possible roundness for the pill effect.

Does this work on images?

Yes, adding `border-radius` to an `img` tag will round its corners or clip it into a circle.
