描述 (Description)

page-break-after属性指示在元素框之后是否应允许（以及多少）分页符。

此属性的值不是确定分页符是否应遵循该元素的唯一因素。此决定还将受到后续元素的page-break-before值以及任何祖先元素的page-break-inside值的影响。

可能的值 (Possible Values)

auto - 在元素框之后既不强制也不阻止分页符。
always - 应在此元素的框后强制分页。
avoid - 如果可能的话，不应在元素框之后放置分页符。
left - 在元素框之后强制一个或两个分页符，以便打印元素的下一页将是左侧页面。
right - 在元素框之后强制一个或两个分页符，以便打印元素的下一页将是右侧页面。

适用于 (Applies to)

所有块级元素。

         Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android.
         The first beta version of the Android Software Development Kit (SDK) was released by Google in 2007 where as the first commercial version, Android 1.0, was released in September 2008.

         The source code for Android is available under free and open source software licenses. Google publishes most of the code under the Apache License version 2.0 and the rest, Linux kernel changes, under the GNU General Public License version 2
