css多行省略也就只有chrome中可以实现，在其他浏览器貌似不行，js去解决的话，又出现一闪的效果。这种体验又不好，哪位大神有更好的解决办法？

比较靠谱简单的做法就是设置相对定位的容器高度，用包含省略号(…)的元素模拟实现；
p {
position:relative;
line-height:1.4em;
/*三倍line-height去显示三行*/
height:4.2em;
/*多余的隐藏*/
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;
}

如果需要跨内核支持，允许固定高的可以借助多层嵌套浮动这么做：
<!doctype html><html><body>
<style>
.ellipsis {
overflow: hidden;
position: relative;
}
.ellipsis-more-top {/*push down .ellipsis-more*/
content: "";
float: left;
width: 5px;
}
.ellipsis-text-container {
float: right;
width: 100%;
margin-left: -5px;
}
.ellipsis-more-container {
float: right;
position: relative;
left: 100%;
width: 5px;
margin-left: -5px;
border-right: solid 5px transparent;
white-space: nowrap;
}
.ellipsis-placeholder {/*keep text around ,keep it transparent ,keep same width and height as .ellipsis-more*/
float: right;
clear: right;
color: transparent;
}
.ellipsis-placeholder-top {/*push down .ellipsis-placeholder*/
float: right;
width: 0;
}
.ellipsis-more {/*ellipsis things here*/
float: right;
}
.ellipsis-height {/*the total height*/
height: 3.6em;
}
</style>
<p class="ellipsis ellipsis-height ellipsis-line-height">
<p class="ellipsis-more-top ellipsis-height"></p>
<p class="ellipsis-text-container">
<p class="ellipsis-placeholder-top ellipsis-height ellipsis-margin-top"></p>
<p class="ellipsis-placeholder">
<span>...</span><span>more</span>
</p>
<span class="ellipsis-text">text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </span>
</p>
<p class="ellipsis-more-container ellipsis-margin-top">
<p class="ellipsis-more">
<span>...</span><span>more</span>
</p>
</p>
</p>
</body></html>如需不定高，可借助line-clamp和float可以在webkit上实现自适应高的定制的多行省略，详细解释看黑科技：CSS定制多行省略
