Unlike character styles or paragraph styles, the page styles don't know a hierarchy. You can create a new page style based on the properties of an existing page style, but when you later change the source style, the new page style does not automatically inherit the changes.
不同于字符样式或段落样式，页面样式不分辨层次结构。您可以基于一个已有页面样式的属性创建一个新的页面样式，但当您后来更改源样式，新的页面样式并不会自动继承这些变化。
