清除浮动方法汇总

1、额外标签

.clear{
clear: both;

}

2、overfloat

.father{

overfloat: hidden;

}

3、伪元素法：clearfix类放到父元素

.clearfix::after{
/* 下面三个属性缺一不可 */
content: "";
display: block;
clear: both;
}

4、双伪元素

.clearfix::after,.clearfix::before{
display: table;
content:"";
}
.clearfix::after{
clear: both;

}
