二.实际应用代码
建议做网站的时候,设置个reset.css样式表清除各个浏览器的默认样式,已达到做的网页在各个浏览器中达到统一,下面把YUI Reset CSS代码贴出
- body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,textarea,p,blockquote,th,td {
- margin:0;
- padding:0;
- }
- table {
- border-collapse:collapse;
- border-spacing:0;
- }
- fieldset,img {
- border:0;
- }
- address,caption,cite,code,dfn,em,strong,th,var {
- font-style:normal;
- font-weight:normal;
- }
- ol,ul {
- list-style:none;
- }
- caption,th {
- text-align:left;
- }
- h1,h2,h3,h4,h5,h6 {
- font-size:100%;
- font-weight:normal;
- }
- q:before,q:after {
- content:'';
- }
- abbr,acronym {
- border:0;
- }
