为了消除各浏览器对css默认的设置，保持网页在各浏览器中的外观保持一致，初始化css就显得非常必要了！很多时候出现的样式不兼容问题，都可以通过css初始化代码来解决。下面列举常用的一些方案：
1.最耗资源的，最简单的
* { padding: 0; margin: 0; border: 0; }
2.选择性初始化举例（综合）
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,legend,button
form,fieldset,input,textarea,p,blockquote,th,td {
padding: 0;
margin: 0;
}
批注：上面的写法有问题，会导致浏览器解析异常。原因不明，推荐使用下面替代方案：
html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed,
figure, figcaption, footer, header, hgroup,
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
margin: 0;
padding: 0;
border: none;
outline: none;
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
或者：
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,form,fieldset,legend,input,textarea,p,blockquote,th,td{margin:0;padding:0;}
/* 酌情修改 */
body {
background:#fff;color:#333;font-size:12px;font-family:"SimSun","宋体","Arial Narrow";
}
/* 短引用的内容可取值：''或"" */
q:before,q:after {content:”;}
/* 缩写，图片等无边框 */
fieldset,img,abbr,acronym {border: 0 none;}
abbr,acronym {font-variant: normal;}
legend {color:#000;}
/* 清除特殊标记的字体和字号 */
address,caption,cite,code,dfn,em,strong,th,var {
font-weight: normal;
font-style: normal;
}
/* 上下标 */
sup {vertical-align: text-top;}
sub {vertical-align: text-bottom;}
/* 设置表格的边框被合并为一个单一的边框, 指定分隔边框模型中单元格边界之间的距离为0*/
table {
border-collapse: collapse;
border-spacing: 0;
}
/* 表格标题及内容居左显示 */
caption,th {text-align: left;}
input,img,select {vertical-align:middle;}
/* 清除列表样式 */
ol,ul {list-style: none;}
/* 输入控件字体 */
input,button,textarea,select,optgroup,option {
font-family:inherit;
font-size:inherit;
font-style:inherit;
font-weight:inherit;
}
/* 标题元素样式清除 */
h1,h2,h3,h4,h5,h6 {
font-weight: normal;
font-size: 100%;
}
/* 链接样式，颜色可酌情修改 */
del,ins,a {text-decoration:none;}
a:link {color:#009;}
a:visited {color:#800080;}
a:hover,a:active,a:focus {color:#c00; text-decoration:underline;}
/* 鼠标样式 */
input[type="submit"] {cursor: pointer;}
button {cursor: pointer;}
input::-moz-focus-inner { border: 0; padding: 0;}

/* 全局样式 */
body,ul,ol,li,p,h1,h2,h3,h4,h5,h6,form,fieldset,table,td,img,div{
