 > - The rounded corner of a button is set by using [Border](ts-universal-attributes-border.md). (The rounded corner cannot be set by using a border API.)
 > - When the button type is **Capsule**, the **borderRadius** settings do not take effect, and the rounded corner of the button is always half of the button height. 
 > - When the button type is **Circle**, the value of **borderRadius** is used as the button radius. If **borderRadius** is not set, the button radius is half of the width or height, whichever is smaller.
