连续字符换行 溢出点点点 多行省略

让连续的英文数字字符换行显示 

word-break: break-all;

 

让单行文字超出的时候使用点点点表示 

white-space: nowrap; overflow: hidden; text-overflow: ellipsis;（移动开发浏览器支持良好）

 

WebKit可以让多行文字点点点（利用Flexbox）：

overflow: hidden; text-overflow: ellipsis;  display: -webkit-box;  -webkit-line-clamp: 3;  -webkit-box-orient: vertical;

 

淡出方式实现：

原理就是设定高度，然后最后那里用淡出做覆盖。例如line-height设为1.2em，然后需要三行文字，那么就把高度设为3.6em，然后把超出的overflow:hidden。在最后添加添加...或者用伪元素（before）半透明遮罩，因为不知道到底有几行字，所以方法就给最后一行整行添加半透明遮罩。

 

opera自己搞了一套：

.last-line {

  height: 3.6em; /* exactly three lines */

  text-overflow: -o-ellipsis-lastline;

}

 

在自适应的表格中，会撑大表格宽度，因为单元格的流动性，使得文字根本就不存在溢出这种说法，这个时候给table使用  table-layout: fixed  作用在于，让表格布局固定，也就是表格的宽度不是跟随单元格内容多少自动计算尺寸

使用表格相关display属性帮助构建web页面，总会遇到类似的连续英文字符不换行，或者单行文字溢出没有效果的。此时，可以用以下方法解决

display:table; 100%; table-layout:fixed;

 

使用line-clamp截断多行文字，出现...

<div class="ellipsis"><div>
  <p>Call me Ishmael.  Some years ago &ndash; never mind how long precisely &ndash; having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.  It is a way I have of driving off the spleen, and regulating the circulation.  Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people's hats off &ndash; then, I account it high time to get to sea as soon as I can. <i></i></p>
