哪位大侠帮我看下，怎么把窗口里的4张小图横排改成竖排。。。
#focustitle {
PADDING-LEFT: 10px; OVERFLOW: hidden; WIDTH: 300px; LINE-HEIGHT: 25px; HEIGHT: 25px
}
.banner22 {
FONT-SIZE: 12px; MARGIN: 0px; WIDTH: 320px; POSITION: relative; HEIGHT: 182px
}
.banner_tab {
RIGHT: 0px; BOTTOM: 10px; POSITION: absolute; HEIGHT: 43px
}
.banner_tab UL {
CURSOR: pointer
}
.banner_tab LI {
FLOAT: left; LIST-STYLE-TYPE: none; TEXT-ALIGN: center
}
.banner_tab A {
DISPLAY: block; WIDTH: 60px; MARGIN-RIGHT: 2px; HEIGHT: 43px
}
.banner_tab IMG {
BORDER-RIGHT: #659ab6 1px solid; BORDER-TOP: #659ab6 1px solid; BORDER-LEFT: #659ab6 1px solid; BORDER-BOTTOM: #659ab6 1px solid
}
.hidecontent {
DISPLAY: none
}
.tab_img {
BORDER-RIGHT: #fff 1px solid; BORDER-TOP: #fff 1px solid; MARGIN-TOP: 3px; BORDER-LEFT: #fff 1px solid; WIDTH: 52px; BORDER-BOTTOM: #fff 1px solid; HEIGHT: 35px
}
