请问怎么改CSS让它只对以下html代码起作用，现有的css好像是控制所有ul li的，但我只想控制下面html代码部分

以下html代码

          
         < >              
          
          
          
          
          
          
          
          
          
          
          
        
    
      
  

 以下CSS代码  
img,ol,ul,li{margin:0;padding:0;}ol, ul{ list-style: none outside none;}.m { margin-bottom: 10px; }.m, .mt, .mc, .mb{ overflow: hidden; }/* Clear Fix */ .clearfix:after{content:".";display:block;height:0;clear:both;visibility:hidden;} .clearfix{display:inline-block;} /* Hide from IE Mac */ .clearfix{display:block;} /* End hide from IE Mac */ /* end of clearfix */ /*页面全局结束*/.tab{ overflow:hidden; }.tab li,.tab a,.tab-item{cursor:pointer;float:left;text-align: center;}.m, .mt, .mc, .mb{overflow:hidden;}.mt .extra{float: right;}.right-extra .mt{height:28px;line-height:28px;padding:0 10px 8px;border-top:1px solid #EED97C;background:url(../images/bg_hotsale.gif) repeat-x 0 -552px;color:#c00;}.right-extra .tab{border-bottom:2px solid #BE0000;margin-bottom:10px;}.right-extra .tab li{position:relative;height:24px;padding:3px 12px 0;background:url(../images/icon_clubs.gif) #ccc no-repeat right -150px;overflow:hidden;margin-right:3px;line-height:24px;font-size:14px;font-weight:bold;color:#c30;}.right-extra .tab span{position:absolute;left:0;top:0;z-index:1;width:10px;height:27px;background:url(../images/icon_clubs.gif) no-repeat 0 -150px;}.right-extra .tab a{float:none;color:#c30;}.right-extra .tab .curr{background-position:right -178px;color:#fff;}.right-extra .tab .curr span{background-position:0 -178px;}.right-extra .tab .curr a{color:#fff;}.right-extra .mc .extra{padding:5px 10px;border-top:1px solid #F3E6C6;}.right-extra .total{float:right;}.right-extra .total strong{color:#FF7403;}.right-extra .total a:link,.right-extra .total a:visited{color:#005aa0;}.right-extra .join a:link,.right-extra .join a:visited{color:#FF7604;}.right-extra .norecode{padding:0 10px 10px;}.right-extra .iloading{margin-bottom:10px;}/*图片放大镜样式*/.jqzoom{float:left;border:none;position:relative;padding:0px;cursor:pointer;margin:0px;display:block;}.zoomdiv{z-index:100;position:absolute;top:0px;left:0px;width:350px;height:350px;background:#ffffff;border:1px solid #CCCCCC;display:none;text-align:center;overflow:hidden;}.jqZoomPup{z-index:10;visibility:hidden;position:absolute;top:0px;left:0px;width:20px;height:20px;border:1px solid #aaa;background:#ffffff /*url(../images/zoom.png) 50% center no-repeat*/;opacity: 0.5;-moz-opacity: 0.5;-khtml-opacity: 0.5;filter: alpha(Opacity=50);}/*图片小图预览列表*/.spec-preview{width:350px;height:350px;border:1px solid #DFDFDF;}.spec-scroll{clear:both;margin-top:5px;width:352px;}.spec-scroll .prev{float:left;margin-right:4px;}.spec-scroll .next{float:right;}.spec-scroll .prev,.spec-scroll .next{display:block;font-family:"宋体";text-align:center;width:10px;height:54px; line-height:54px;border:1px solid #CCC;background:#EBEBEB;cursor:pointer;text-decoration:none;}.spec-scroll .items{float:left;position:relative;width:322px;height:56px;overflow:hidden;}.spec-scroll .items ul{position:absolute;width:999999px;height:56px;}.spec-scroll .items ul li{float:left;width:64px;text-align:center;}.spec-scroll .items ul li img{border:1px solid #CCC;padding:2px;width:50px;height:50px;}.spec-scroll .items ul li img:hover{border:2px solid #FF6600;padding:1px;}
    
  
回复讨论(解决方案)
   类似这样的  

.right-extra ul li {.....}
    CSS代码里面的ul、cl就是针对class="items"的呀  
.spec-scroll .items ul{position:absolute;width:999999px;height:56px;}.spec-scroll .items ul li{float:left;width:64px;text-align:center;}.spec-scroll .items ul li img{border:1px solid #CCC;padding:2px;width:50px;height:50px;}.spec-scroll .items ul li img:hover{border:2px solid #FF6600;padding:1px;}
  
 这里只是对全局ul、cl初始化  img,ol,ul,li{margin:0;padding:0;} ol, ul{ list-style: none outside none;}
