Frequently Asked Questions

Border-radius is a CSS property that rounds the corners of an element's border box. You can round all corners equally or each corner individually for creative shapes like pills, blobs, and speech bubbles.
Uniform mode applies the same radius to all four corners. Individual mode lets you set different values for each corner (top-left, top-right, bottom-right, bottom-left), allowing for asymmetric shapes.
px (pixels) is most common for fixed sizes. % creates corners relative to the element's dimensions (50% makes a circle from a square). em/rem are useful for responsive designs that scale with font size.
Set border-radius to 50% on a square element (equal width and height). The 'Pill' preset uses 9999px which rounds the ends of any rectangular element into a pill shape.
