CSS Reset是指重设浏览器的样式。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。

下面介绍几个主流的CSS Reset代码
1、Eric Meyer

复制代码
代码如下:

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, sub, sup, tt, 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: 0;
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure,
footer, header, hgroup, menu, nav, section {
display: block;
}
body {
line-height: 1;
}
ol, ul {
list-style: none;
}
blockquote, q {
quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
content: '';
content: none;
}
table {
border-collapse: collapse;
border-spacing: 0;
}

2、YUI

代码如下:

*/
/*
TODO will need to remove settings on HTML since we can't namespace it.
TODO with the prefix,should I group by selector or property for weight savings?
*/
html {
color:#000;
background:#FFF;
}
/*
TODO remove settings on BODY since we can't namespace it.
*/
/*
TODO test putting a class on HEAD.
- Fails on FF.
*/
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;
}
table {
border-collapse:collapse;
border-spacing:0;
}
fieldset,img {
border:0;
}
/*
TODO think about hanlding inheritence differently,maybe letting IE6 fail a bit...
*/
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;
font-variant:normal;
}
/* to preserve line-height and selector appearance */
sup {
vertical-align:text-top;
}
sub {
vertical-align:text-bottom;
}
input,textarea,select {
font-family:inherit;
font-size:inherit;
font-weight:inherit;
}
/*to enable resizing for IE*/
input,textarea,select {
*font-size:100%;
}
/*because legend doesn't inherit in IE */
legend {
color:#000;
}

3、csslab

复制代码
代码如下:

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, font, img, ins, kbd, q, s, samp, small, strike, sub, sup, tt, var, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, dialog, figure, header, footer, hgroup, menu, nav, section, time, mark, audio, video {
margin: 0;
padding: 0;
border: 0;
outline: 0;
font-weight: inherit;
font-style: inherit;
font-size: 100%;
}
article, aside, nav, section, dialog, figure, header, footer, hgroup {
display:block;
}
legend {
display:none;
}
:focus {
outline: 0;
}
table {
border-collapse: collapse;
border-spacing: 0;
}
caption, th, td {
text-align: left;
font-weight: normal;
}
a img, iframe {
border: none;
}
ul {
list-style: none;
}
input, textarea, select, button {
font-size: 100%;
font-family: inherit;
}
input, select {
vertical-align:middle;
}
select {
margin: inherit;
}
button {
border: 0;
padding: 0;
background: transparent;
cursor: pointer;
}
/* Fixes incorrect placement of numbers in ol's in IE6/7 */
ol { margin-left:2em; }
/* ========================================= clearfix == */
.clearfix:after {
content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.clearfix {display: inline-block;}
* html .clearfix {height: 1%;}
.clearfix {display: block;}

需要说明的是CSS Reset并不是一成不变的,具体还需要根据项目的不同需求做适当的修改,以达到浏览器的兼容和操作上的便利性。
