<p style="margin: 10px auto; padding: 0px; list-style-type: none; list-style-image: none; color: rgb(68, 68, 68); font-family: Tahoma, Arial, Helvetica, sans-serif; white-space: normal; background-color: rgb(255, 255, 255);">如果实现单行文本的溢出显示省略号同学们应该都知道用text-overflow:ellipsis属性来，当然还需要加宽度width属来兼容部分浏览。<p style="margin: 10px auto; padding: 0px; list-style-type: none; list-style-image: none; color: rgb(68, 68, 68); font-family: Tahoma, Arial, Helvetica, sans-serif; white-space: normal; background-color: rgb(255, 255, 255);">实现方法：<pre class="prettyprint" style="margin-top: 0px;

white-space: normal; background-color: rgb(255, 255, 255);">但是这个属性只支持单行文本的溢出显示省略号，如果我们要实现多行文本溢出显示省略号呢。<p style="margin: 10px auto; padding: 0px; list-style-type: none; list-style-image: none; color: rgb(68, 68, 68); font-family: Tahoma, Arial, Helvetica, sans-serif; white-space: normal; background-color: rgb(255, 255, 255);">接下来重点说一说多行文本溢出显示省略号，如下。<p style="margin: 10px auto; padding: 0px; list-style-type: none;
