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>
