css初始化代码方案

　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,buttonform,fieldset,input,textarea,p,blockquote,th,td {   　　padding: 0;   　　margin: 0;   }/* 酌情修改 */body {    background:#fff;color:#333;font-size:12px; margin-top:5px;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;}.clear {clear:both;}

3.sina的

/* 全局样式 */body,ul,ol,li,p,h1,h2,h3,h4,h5,h6,form,fieldset,table,td,img,div{    margin:0;padding:0;border:0;}body{    background:#fff;color:#333;font-size:12px; margin-top:5px;font-family:"SimSun","宋体","Arial Narrow";}ul,ol{    list-style-type:none;}select,input,img,select{    vertical-align:middle;}a{text-decoration:none;}a:link{color:#009;}a:visited{color:#800080;}a:hover,a:active,a:focus{color:#c00;text-decoration:underline;}
