Frequently asked questions
What's the 8-value syntax?
border-radius can take horizontal and vertical radii per corner, enabling smooth, asymmetric blob shapes.

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.
