3、请将以下代码缩写： [缩写基本功]

#box {
margin-top:5px;
margin-bottom:4px;
margin-left:8px;
margin-right:5px;
float:left;
border-left-style:solid;
border-left-border:1px;
border-left-color:#000000;
border-right-style:solid;
border-right-border:1px;
border-right-color:#000000;
border-bottom-style:dashed;
border-bottom-border:1px;
border-bottom-color:#FF0000;
background-color:#FF6600;
background-image: url(/resources/img/pagearr2.gif);
background-repeat: no-repeat;
background-position:left top;
}

答案：#box{

        margin:5px 4px px

       float:left; 

　　  border-left:1px solid #000

       border-right:1px solid #000

       border-bottom:1px dashed #ff00

       background:url(/resources/img/pagearr2.gif) #rr6600 not-repeat

      background-position:left top

}
