What is Border Radius?
CSS border-radius rounds element corners. This tool gives per-corner control (top-left, top-right, bottom-right, bottom-left) with live preview.
How it works
Adjust each corner radius independently; we render a preview box and emit the border-radius CSS shorthand or individual properties.
