fieldset, img,input,button { border:0 none; padding:0;margin:0;outline-style:none; }   /*去掉input等聚焦时的蓝色边框*/
ul,li,ol{ list-style:none; }

/* 行内元素的垂直居中 */
/* 
vertical-align：top 

*/
select, input { vertical-align:middle;}
/*select, input, textarea { font-size:12px; margin:0; }*/
textarea { resize:none; } /*防止拖动*/
img {border:0; vertical-align:middle; }  
/*  去掉图片低测默认的3像素空白缝隙，或者用display：block也可以*/
/* table { border-collapse:collapse; } */

a {text-decoration:none; }

/*（2）添加公共样式*/

    font:12px Arial,Verdana,"\5b8b\4f53";
