CSS Reset
设置字体: 小 中 大知道CSS Reset是什么吗?通常情况下,它也被写成Reset CSS,即重设浏览器的样式。在各种浏览器中,都会对CSS的选择器默认一些数值,譬如当h1没有被设置数值时,显示一定大小。但并不是所有的浏览器都使用一样的数值,所以,有了CSS Reset,以让网页的样式在各浏览器中表现一致。
正在使用CSS的你,用过CSS Reset吗?当然,或许你用了,却不知道正在用,比如你可能用到:
- * { padding: 0; margin: 0; border: 0; }
这也是一款CSS Reset的方法,让所有的选择器的padding、margin和border都设置成0。这是一种强大的方法,也是最简单,最安全的方法,不过,也是最占用资源的方法。对于小型的网站来说,用这个并不会带来大的资源浪费,但如果是像Yahoo这种架构非常大的网站,刚需要有选择地进行CSS重设,以减少资源浪费。下面是Yahoo的CSS重设代码,也是受最多人喜爱的CSS Reset方法,YUI选择的方法是:
- body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,
- form,fieldset,input,textarea,p,blockquote,th,td {
- padding: 0;
- margin: 0;
- }
- table {
- border-collapse: collapse;
- border-spacing: 0;
- }
- fieldset,img {
- border: 0;
- }
- address,caption,cite,code,dfn,em,strong,th,var {
- font-weight: normal;
- font-style: normal;
- }
- ol,ul {
- list-style: none;
- }
- caption,th {
- text-align: left;
- }
- h1,h2,h3,h4,h5,h6 {
- font-weight: normal;
- font-size: 100%;
- }
- q:before,q:after {
- content:”;
- }
- abbr,acronym { border: 0;
- }
OK,相信你也已经了解了CSS重设的目的,或许你也可以根据自己的喜好,写一个自己的CSS重设系统,毕竟大家的需求和习惯的不同的。而你可以参照下面的几款:

像你看到的,这些都大同小异,需求不同,方法也就不同。我自己偏向于喜欢Yahoo的CSS Reset,也用了Yahoo的代码。你,有自己的CSS Reset体系吗?或许可以分享出来!
