Some problems to understand CSS paged media style

Question

I have some doubt about the paged media in CSS.

If I have something like this code:

@page rotated {size: landscape}
TABLE {page: rotated; page-break-before: right}

what exactly happen? can you explain to me this code? I am reading the documentation but I am finding some problems...

Tnx Andrea

它似乎是一个在打印时应用的规则，如果浏览器遇到文档中的元素并且当前页面布局是默认的纵向布局，它将启动一个新页面并在横向页面上打印该表。
