CSS corner-shape playground

Experiment with corner-shape and border-radius to build rounded, beveled, notched, or scooped corners by corner or pair with modern CSS.

CSS output

Shorthand output groups values into CSS shorthands when possible. Individual output generates one declaration per property so each value can be reviewed or copied separately.

Shorthand Individual

Application

Choose how values are distributed: apply one value to the whole element or adjust only the sides, axes, or groups you need.

All Individual Corner pairs

Property system

Physical properties apply directly to the element's sides, while logical properties apply to the element's sides based on the text direction.

With logical properties, it is important to check how results change in languages written left to right and right to left.
