假设我们有如下代码

  


    

  

会发现效果如下所示

子元素的margin-top并没有使子元素与父元素分开,反倒效果等同于给父元素加了一个margin-top;

解决的方法也有,具体为:

1.修改父元素的高度,增加padding-top样式模拟(padding-top:1px;)

2.为父元素添加overflow:hidden;

3.为父元素或者子元素生命元素浮动(float:left;可用但是不推荐)

4.为父元素添加border(border:1px solid transparent)

5.为父元素或者子元素声明绝对定位

6.给父元素增加内容生成#father:before{content:' ';display:table};
