HTML Style isolation用法及代碼示例

DOM樣式隔離屬性定義元素是否必須創建新的堆棧上下文。

用法:

返回隔離語法：
```
object.style.isolation
```

設置隔離語法：

object.style.isolation = "auto|isolate|initial|inherit"

屬性：

auto:它是默認屬性值。使用此屬性，如果應用於元素的屬性之一需要，則僅創建一個新的堆棧上下文。
isolate:它指出必須創建一個新的堆棧上下文，而不會出現任何故障。
initial:它將隔離屬性設置為其默認值。
inherit:它繼承了父元素的隔離屬性值。

返回值：它返回元素的堆疊上下文。

示例1：顯示自動屬性。
