# concentric(minimum:)

A rounded corner style where the corner’s radius shares a center point with the container shape’s corner radius, with an optional minimum radius.

## Declaration

```swift
static func concentric(minimum: Edge.Corner.Style? = nil) -> Edge.Corner.Style
```

## Discussion

Discussion When a corner is concentric to its container, the system calculates the corner radius to equal the container shape’s corner radius minus the distance between corners. If the radius that the system calculates is less than the minimum radius you provide, the system uses the minimum radius. When the system calculates a zero radius, the corner is square.
