Overview

CSS Border Radius Generator designs per-corner radius values, preview shapes, and implementation-ready CSS for cards, controls, avatars, and custom UI surfaces. The native Toolars workspace migrates the Aixtral shorthand behavior into stable numeric controls, keeps values local, shows whether output is simplified or expanded, and gives designers copy-ready border-radius declarations before styling changes ship.
