我有完美的工作代码,它不能按照我想要的方式工作......但是可以工作。
我想居中而不是 float
这是工作代码:
我的.css:
* {
margin: 0;
padding: 0;
}
body { background: #ededed url(../images/bg.gif) repeat-x; }
p {

}
#container {

}
#header {

width: 950px;
float: left;
background: url(../images/header.gif) no-repeat;
}
#logo { margin-top: 60px; }

然后我尝试通过以下方式使 div 成为中心:
#content-center {
margin-left: auto ;
margin-right: auto ;
width: 322px;
margin-top: 20px;
}
但是它弄乱了上面的 div。
添加这个:
#content_center {
margin-left: auto ;
margin-right: auto ;
width: 322px;
margin-top: 20px;
clear: both;
}
左侧或右侧都不允许有 float 元素(由于 clear: both
)。
