为了让页面在各不同浏览器之间显示效果一致，css样式清除和重置工作是必须的，整理了些代码，分享下。
复制代码 代码示例:
@charset "utf-8";
body, h1, h2, h3, h4, h5, h6, hr, p, blockquote, pre,
dl, dt, dd, ul, ol, li, th, td, div, span, img,
fieldset, lengend, button, input, select, textarea{margin: 0;padding: 0;}
/* color & background */
html{color:#000; background:#FFF;}
/* font */
body, button, input, select, textarea { /* for ie */
font: 12px/18px Arial, Verdana, Microsoft YaHei;
}
/* fix center */
html,body {height: 100%;margin: 0 auto;}
/* h1~h6 */
h1 {font-size: 18px;}
h2 {font-size: 16px;}
h3 {font-size: 14px;}
h4, h5, h6 {font-size: 100%;}
/* a */
a { text-decoration: none; }
a:hover { text-decoration: underline; }
/* list */
ul,ol {list-style: none;}
/* img border */
fieldset,img{border: 0}
