css初始化代码方案

（从已经死了一次又一次终于挂掉的百度空间人工抢救出来的，发表日期 2014-06-24）

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;}
