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; } /* 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;}
