小編這裏有一篇總結css reset以及IE兼容css教程3圓角的htc解決方法 ，屬於比較全面的文章，希望能對大家有所幫助。
重置默認樣式
最近看到一個詞叫css reset。什麼叫做css reset呢?我理解爲重置css，也就是重置默認樣式。我在中講到，一些標籤元素在HTML下有一個默認屬性值，我們在寫css頁面的時候，爲了避免在css中重複定義它們，我們需要重置默認樣式(css reset)。每個人的用法和寫法都不一樣。找到一篇關於 可以看看國外使用css reset的比例調查。
接下來我也查看了國內的兩個網站，用Firebug按F12看看他們的css reset怎麼寫的?
淘寶()：
html {
overflow-x:auto;
overflow-y:scroll;
}
body, dl, dt, dd, ul, ol, li, pre, form, fieldset, input, p, blockquote, th, td {
font-weight:400;
margin:0;
padding:0;
}
h1, h2, h3, h4, h4, h5 {
margin:0;
padding:0;
}
body {
background-color:#FFFFFF;
color:#666666;
font-family:Helvetica,Arial,sans-serif;
font-size:12px;
padding:0 10px;
text-align:left;
}
select {
font-size:12px;
}
table {
border-collapse:collapse;
}
fieldset, img {
border:0 none;
}
fieldset {
margin:0;
padding:0;
}
fieldset p {
margin:0;
padding:0 0 0 8px;
}
legend {
display:none;
}
address, caption, em, strong, th, i {
font-style:normal;
font-weight:400;
}
table caption {
margin-left:-1px;
}
hr {
border-bottom:1px solid #FFFFFF;
border-top:1px solid #E4E4E4;
border-width:1px 0;
clear:both;
height:2px;
margin:5px 0;
overflow:hidden;
}
ol, ul {
list-style-image:none;
list-style-position:outside;
list-style-type:none;
}
caption, th {
text-align:left;
}
q:before, q:after, blockquote:before, blockquote:after {
content:"";
}
百度有啊()：(架構基本上是模仿YUI來做的)
body {
font-family:arial,helvetica,sans-serif;
font-size:13px;
font-size-adjust:none;
font-stretch:normal;
font-style:normal;
font-variant:normal;
font-weight:normal;
line-height:1.4;
text-align:center;
}
body, ul, ol, dl, dd, h1, h2, h3, h4, h5, h6, p, form, fieldset, legend, input, textarea, select, button, th, td {
margin:0;
padding:0;
}
h1, h2, h3, h4, h5, h6 {
font-size:100%;
font-weight:normal;
}
table {
font-size:inherit;
}
input, select {
font-family:arial,helvetica,clean,sans-serif;
font-size:100%;
font-size-adjust:none;
font-stretch:normal;
font-style:normal;
font-variant:normal;
font-weight:normal;
line-height:normal;
}
button {
overflow:visible;
}
th, em, strong, b, address, cite {
font-style:normal;
font-weight:normal;
}
li {
list-style-image:none;
list-style-position:outside;
list-style-type:none;
}
img, fieldset {
border:0 none;
}
ins {
text-decoration:none;
}
在《超越css》一書中建議我們做網站開始重置所有默認樣式：
/* Normalizes margin,padding */
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,p,blockquote,th,td { margin:0;padding:0}
/* Normalizes font-size for headers */
h1,h2,h3,h4,h5,h6 { font-size:100%}
/* Removes list-style from lists */
ol,ul { list-style:none }
/* Normalizes font-size and font-weight to normal */
address,caption,cite,code,dfn,em,strong,th,var { font-size:normal; font-weight:normal }
/* Removes list-style from lists */
table { border-collapse:collapse; border-spacing:0 }
/* Removes border from fieldset and img */
fieldset,img { border:0 }
/* Left-aligns text in caption and th */
caption,th { text-align:left }
/* Removes quotation marks from q */
q:before,q:after { content:''}
那我們實際寫代碼的時候該怎麼來css reset呢?
我個人推薦使用(和)的 css reset
Eric Meyer's Reset:
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, 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 {
margin: 0;
padding: 0;
border: 0;
outline: 0;
font-size: 100%;
vertical-align: baseline;
background: transparent;
}
body {
line-height: 1;
}
ol, ul {
list-style: none;
}
blockquote, q {
quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
content: '';
content: none;
}
/* remember to define focus styles! */
:focus {
outline: 0;
}
/* remember to highlight inserts somehow! */
ins {
text-decoration: none;
}
del {
text-decoration: line-through;
}
/* tables still need 'cellspacing="0"' in the markup */
table {
border-collapse: collapse;
border-spacing: 0;
}
YUI:
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;
}
結合他們的'css reset寫法，再根據自己的實際情況，一定能寫出符合自己網站的完美的css reset。
