Frequently asked questions

What's the 8-value syntax?

border-radius can take horizontal and vertical radii per corner, enabling smooth, asymmetric blob shapes.

Can I make a circle?

Set every corner to 50% on a square element to get a perfect circle.

Is the output standard CSS?

Yes — copy and paste the border-radius value directly.
