当我在Firefox上使用下面的CSS代码时,我会在横幅和屏幕顶部之间产生差距.我怎么能避免这个？
#container1
{
position:absolute;
left: 0px;
right: 0px;
width: 1000px;
height: 255px;
margin: 0;
}
#logo1 {
background:#FFFFFF;
margin: 0;
border: 1px solid red;
position:absolute;
left: 0px;
top: 0px;
width: 200px;
height: 250px;
}
#Banner1 {
background: #1071A6;
position:absolute;
left: 200px;
top: 0px;
width: 789px;
height: 250px;
vertical-align:top;
margin: 0; border: 1px solid red;
}
