HTML Style borderTopRightRadius用法及代碼示例

DOM樣式的borderTopRightRadius屬性用於設置或返回元素右上邊界的半徑。

用法:

獲取borderTopRightRadius屬性
```
object.style.borderTopRightRadius
```

設置borderTopRightRadius屬性

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

屬性值：

length:用於定義固定長度單位的半徑。可以使用兩個值來指定四分之一橢圓的半徑，第一個值是水平半徑，第二個值是垂直半徑。

示例1：使用一個值指定半徑。
