HTML Style borderTopRightRadius用法及代码示例

DOM样式的borderTopRightRadius属性用于设置或返回元素右上边界的半径。

用法:

获取borderTopRightRadius属性
```
object.style.borderTopRightRadius
```

设置borderTopRightRadius属性

object.style.borderTopRightRadius = "length | percentage | 
initial | inherit"

属性值：

length:用于定义固定长度单位的半径。可以使用两个值来指定四分之一椭圆的半径，第一个值是水平半径，第二个值是垂直半径。

示例1：使用一个值指定半径。
