Frequently asked questions

Can I set each corner separately?

Yes — control the top-left, top-right, bottom-right and bottom-left radii independently for asymmetric shapes.

How do I make a pill or circle?

A very large radius (or 9999px) makes pill buttons, and 50% on a square element produces a perfect circle.

What are the two values per corner for?

Border-radius accepts a horizontal and vertical radius per corner, letting you create elliptical, organic blob corners.
