FAQ
Common questions and answers about this topic.
Can I set different radii for each corner?
Yes, customize each corner independently — top-left, top-right, bottom-right, and bottom-left — or set all corners at once using the 'All Corners' control.
What units are supported?
Both pixels (px) and percentages (%) are supported. Use percentages to create responsive shapes like circles (50%) or pill shapes.
Can I create circles or pill shapes?
Yes, set all corners to 50% for a perfect circle on a square element, or use large pixel values for a pill/capsule shape on rectangular elements.
Is my data sent to any server?
No, border-radius CSS generation is handled entirely in your browser. Your radius values are processed locally — no data is uploaded.
