在網(wǎng)頁<head>區(qū)添加以下代碼

<style type="text/css">  
<!--  
BODY {  
PADDING-RIGHT: 0px; PADDING-LEFT: 0px; FONT-SIZE: 12px; PADDING-BOTTOM: 0px; MARGIN: 0px auto; COLOR: black; LINE-HEIGHT: 150%; PADDING-TOP: 10px; BACKGROUND-COLOR: white; TEXT-ALIGN: center  
}  
.dis {  
DISPLAY: block  
}  
.undis {  
DISPLAY: none  
}  
#cntR {  
WIDTH: 302px  
}  
#NewsTop {  
CLEAR: both; MARGIN-BOTTOM: 16px  
}  
#NewsTop P {  
FLOAT: left; LINE-HEIGHT: 21px  
}  
#NewsTop P.topTit {  
FONT-WEIGHT: bold; WIDTH: 117px  
}  
#NewsTop P.topC0 {  
BACKGROUND: #dcdcdc; BORDER-LEFT: #f2f2f2 1px solid; WIDTH: 40px; CURSOR: pointer  
}  
#NewsTop P.topC1 {  
BACKGROUND: #c2130e; BORDER-LEFT: #f2f2f2 1px solid; WIDTH: 40px; COLOR: #fff  
}  
#NewsTop #NewsTop_tit {  
BORDER-BOTTOM: #c2130e 3px solid; HEIGHT: 21px

#NewsTop #NewsTop_cnt {  
PADDING-LEFT: 32px; BACKGROUND: url(http://www.dhdzp.com/code/table/tab/o2007320133249.gif) no-repeat 12px 13px; LINE-HEIGHT: 26px; PADDING-TOP: 7px; HEIGHT: 260px; TEXT-ALIGN: left

#NewsTop #NewsTop_cnt A:hover {  
COLOR: #c2130e; TEXT-DECORATION: underline  
}

</style>
