FAQ

Can I round each corner differently?

Yes. Switch from Linked to Per corner and each slider controls one corner. The tool writes the shorthand in top-left, top-right, bottom-right, bottom-left order.

How do I make a pill or circle shape?

Use the Pill preset, or set every corner to a large value. A fully rounded pill uses a radius larger than half the element's height; a perfect circle needs a square element with a 50% radius.

Is the generated CSS production-ready?

Yes. It collapses to a single value when all corners match, and falls back to the four-value shorthand when they differ. Paste it straight into your stylesheet or a Tailwind arbitrary value.
