css 超出规定行数自动隐藏
单行
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
//多行超出长度隐藏
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: 2;//向显示多少行就给多大值
-webkit-box-orient: vertical;
多行(兼容各个浏览器)//通过覆盖最后几个字的形式
p{
position:relative;
line-height:1.4em;
height:4.2em;/* 3 倍line-height 多少倍就是多少行*/
overflow:hidden;
}
.p::after {
content:"...";
font-weight:bold;
position:absolute;
bottom:0;
right:0;
padding:0 20px 1px 45px;
background: -webkit-linear-gradient(left, transparent, #fff 55%);
background: -o-linear-gradient(right, transparent, #fff 55%);
background: -moz-linear-gradient(right, transparent, #fff 55%);
background: linear-gradient(to right, transparent, #fff 55%);
}
效果如下
