@charset "utf-8";
*{padding:0;margin:0;}
.page {
	font-size: 14px;
	text-align:center
}
.page ul{list-style-type:none;display:table;margin-left:auto;margin-right:auto}
.page ul li{min-width:20px;padding:5px;margin-left:3px;border:1px solid #CCC;text-align:center;float:left;*float:none;*display:inline;*zoom:1;}
.page .select{font-weight:bold;color:#000;font-size:14px;background-color:#F5F5F5;}
.page li a{text-decoration:none;color:#333}
.page .gray{color:#808080}
