.g-cf {zoom:1;}
/*分页*/

.g-pager a,.g-pager input{ cursor:pointer; border:solid 1px #0F71BE; padding:1px 4px; color:#0F71BE; margin:0 2px; vertical-align:middle; }
.g-pager a.cur,.g-pager a:hover{ background-color:#0F71BE; color:#fff}

.g-pagerwp{ height:23px; line-height:23px;padding:5px; margin-bottom:10px; border: 1px solid #DDDDDD;}
