今天学习到了一个非常神奇的css布局方法
position: absolute;
top:61px;
bottom: 0px;
把 position设置为 absolute 后 top就是顶边拉 left就是左边拉
那么如果把 底边调成0.嘿嘿,是不是变成窗口自适应了?
做这个的时候想过 直接设置 height:100%.但是这是无效帝,,,具体为什么我也不知道哈...
[css]
#head{
width:100%;
height:61px;
border-bottom:solid 1px #ccc;
background-image:url(../img/topbg.gif);
background-repeat:repeat-x;
}
#logo{
width:189px;
height:61px;
background-image:url(../img/logo_dmin.png);
}
#left{
padding-top:15px;
width:205px;
height:auto;
overflow-y:auto;
background-image: url(../img/leftbg.gif);
position: absolute;
top:61px;
bottom: 0px;
}
#left h4{
margin-left:18px;
background-image:url(../img/menuf.gif);
height: 20px;
width: 160px;
font-size: 12px;
