Frequently Asked Questions
What is CSS border-radius?
CSS border-radius is a property that allows you to round the corners of an element. You can control each corner individually or set them all at once.
Can I create circular elements?
Yes! Set border-radius to 50% on a square element to create a perfect circle. For rectangles, 50% creates elliptical shapes.
What's the difference between px and % units?
Pixels (px) are absolute units - 10px is always 10 pixels. Percentages (%) are relative to the element's dimensions - 50% creates a circle on a square.
Can I create elliptical corners?
Yes! Elliptical corners use two values: horizontal-radius/vertical-radius (e.g., border-radius: 50px/25px). Our tool supports this through the elliptical mode.
Is border-radius supported in all browsers?
Yes! CSS border-radius is supported in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. It's also supported in IE9 and above.
How do I apply border-radius to images?
Simply apply the border-radius CSS property to your img element or its container. The image corners will be rounded accordingly.
