The Seventeenth Day of PHP Practice_PHP Tutorial
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...

#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;
