The code is as follows:
.....
#a{
width:100px;
height:100px;
background- color:red;
border:5px solid #bbbbbb;
float:left;
}
#b{

My question Yes, why does it display "normal" under IE7

but "abnormal" under IE8/9, firefox and chrome? So how do I display it normally under IE8/9, firefox and chrome? ?
