div里面的内容超出自身高度时，显示省略号

本文主要是介绍div里面的内容超出自身高度时，显示省略号，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.给DIV设置属性：width: 200px; text-overflow: ellipsis; overflow: hidden; 当div里面的内容总宽度找过 200PX的时候，超出的部分会以“...”的形式显示。

2.上面那个案例之适用于单行文本的现实，才会有效。但当div里面的内容出现多行的时候则不能达到预期的效果。下面是解决多行的时候显示“...”的方案。

You probably can't do it (currently?) without a fixed-width font like Courier. With
a fixed-width font every letter occupies the same horizontal space, so you could
probably count the letters and multiply the result with the current font size in
ems or exs. Then you would just have to test how many letters fit on one line, and
then break it up.</p>
