复制代码 代码如下:

body, span, div, td { font-size:12px; line-height:1.5em; color:#849BCA; }
#bodyL { float:left; width:84px; margin-right:2px; }
a.od { width:80px; height:25px; line-height:25px; text-align:center; font-weight:bold; border: 2px solid #849BCA; display:block; color:#547BC9; float:left; text-decoration:none; margin-top:2px; }
a.od:link { background:#EEF1F8; }
a.od:visited { background:#EEF1F8; }
a.od:hover { background:#EEE; }
a.od:active { background:#EEE; }
#fd { width:500px; height:200px; background:#EDF1F8; border: 2px solid #849BCA; margin-top:2px; margin-left:2px; float:left; overflow:hidden; position:absolute; left:0px; top:0px; cursor:move; float:left;/*filter:alpha(opacity=50);*/ }
.content { padding:10px; }
