? Frequently Asked Questions
How does border-radius work?
Border-radius rounds element corners. Values can be pixels, percentages, or ems. You can specify all corners at once (border-radius: 10px) or each corner individually (top-left, top-right, bottom-right, bottom-left).
Can I create elliptical rounded corners?
Yes! Use two values separated by a slash: border-radius: 50px / 25px. The first value is horizontal radius, the second is vertical, creating elliptical curves instead of circular ones.
How do I make a perfect circle?
Set border-radius: 50% on a square element. The percentage is relative to the element's dimensions, so 50% on a square creates a circle. For rectangles, use a large pixel value instead.
Can each corner have different radius values?
Absolutely! You can specify different values for each corner: border-radius: 10px 20px 30px 40px (top-left, top-right, bottom-right, bottom-left) or use individual properties like border-top-left-radius.
Does it work with border and padding?
Yes, border-radius interacts with borders and padding. The outer edge follows the border, while inner edge adjusts for padding. The visual preview helps you see how these properties combine.
