CSS实现单行、多行文本溢出显示省略号

方法一：只显示3行，在第三行结尾显示...

 p{display: -webkit-box;
 -webkit-box-orient: vertical;
 -webkit-line-clamp: ;
 overflow: hidden;
 }

方法二：适用性更广，未超出部分也会出现...

 p{
   position: relative;
   line-height: 20px;
   max-height: 40px; /*是行高的整数倍，防止下行文字露出*/
   overflow: hidden;
 }

 p::after{
   content: "..."; position: absolute; bottom: ; right: ; padding-left: 40px;
   background: -webkit-linear-gradient(left, transparent, #fff %);
   background: -o-linear-gradient(right, transparent, #fff %);
   background: -moz-linear-gradient(right, transparent, #fff %);
   background: linear-gradient(to right, transparent, #fff %);
 }
