CSS - page-break-after

page-break-after 属性指示在元素的盒子之后是否（以及多少）允许分页符。

此属性的值不是决定是否应该在元素之后添加分页符的唯一因素。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

auto − 在元素的盒子之后，既不强制也不阻止分页符。
always − 在此元素的盒子之后强制分页符。
avoid − 尽可能避免在元素的盒子之后放置分页符。
left − 在元素的盒子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 − 在元素的盒子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。

应用于

所有块级元素。

示例

以下是一个示例：

<html>
   <head> 
   
      <style type = "text/css">
         p {page-break-after: always;}
      </style>
   </head>

   <body>

         Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies.
         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.
         On June 27, 2012, at the Google I/O conference, Google announced the next Android version, 4.1 Jelly Bean. Jelly Bean is an incremental update, with the primary aim of improving the user interface, both in terms of functionality and performance.
         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
