在webkit浏览器下，可以这么写
padding
left-2">
overflow : hidden; text-overflow: ellipsis; display: -webkit-box; -webkit-line-clamp: 2; -webkit-box-orient: vertical;
<p>WebKit Browsers will clamp the number of lines in this paragraph to 2. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p> <style> p { position:relative; line-height:1.4em; /* 3 times the line-height to show 3 lines */ height:4.2em; overflow:hidden; } p::after { content:"..."; font-weight:bold; position:absolute; bottom:0; right:0; padding:0 20px 1px 45px; background:url(http://css88.b0.upaiyun.com/css88/2014/09/ellipsis_bg.png) repeat-y; } </style>
还有一种实现方法是用插件，如 Clamp.js
