我有一个960网格系统的问题。
我的英语不是很好，所以我给你看一张图片，我的意思是:
https://picr.ws/images/0651e9daf54838f294450fae875b25e5.png我想把底部的grid_4推到顶部的grid_4，而不是留在grid_8下面。下面是我的代码:
.container {
width: auto;
height: auto;
padding: 20px;
margin-bottom: 20px;
border: 1px solid #dedede;
background-color: #fff;
position: relative;
}
.container .title {
font-weight: 400;
font-size: 14pt;
}
.container .content {
font-size: 10pt;
