CSS:Cascading Style Sheets(层叠样式表)
有三种方式可以在XHTML页面中嵌入CSS.参见CSS教程.
<
head
>
<
link
rel
=
"
stylesheet
"
type
=
"
text/css
"
href
=
"
style.css
"
/>
</
head
>
此例使用了link标签.
abbr
{
font-size
:
12px
;
}
.text10pxwhite
{
font-size
:
10px
;
color
:
#FFFFFF
;
}
style.css的内容
<
head
>
<
style
type
=
"
text/css
"
>
abbr
{
font-size: 12px;
}
.text10pxwhite
{
font-size: 10px;
color: #FFFFFF;
}
</
style
>
</
head
>
此例使用了style标签.
两种方法是殊途同归的(但是推荐使用第一种方法,在CSS教程中我将告诉你为什么).
<
p
style
=
"
font-size: 12px;color: #000;
"
>
使用css
</
p
>
HTML style 标签
<style>
开始,以</style>
结束media
-- 媒体类型,参见CSS高级教程type
-- 包含内容的类型,一般使用type="text/css"
<
head
>
<
style
type
=
"
text/css
"
>
abbr
{
font-size: 12px;
}
.text10pxwhite
{
font-size: 10px;
color: #FFFFFF;
}
</
style
>
</
head
>
HTML link 标签
<
head
>
<
link
rel
=
"
stylesheet
"
type
=
"
text/css
"
href
=
"
style.css
"
/>
</
head
>
HTML rel rev属性
appendix
-- 定义文档的附加信息bookmark
-- 书签chapter
-- 当前文档的章节contents
copyright
-- 当前文档的版权glossary
-- 词汇help
-- 链接帮助信息index
-- 当前文档的索引nofollow
-- 不被用于计算PageRanksection
-- 作为文档的一部分subsection
-- 作为文档的一小部分rel与rev属性相同,它们都是属于LinkTypes属性.
<
link
rel
=
"
stylesheet
"
href
=
"
http://www.dreamdu.com/style.css
"
type
=
"
text/css
"
>
rel与rev具有互补的作用,rel指定了向前链接的关系,rev指定了反向链接的关系.
HTML alternate 属性值
定义两种不同的样式,用户可以通过浏览器选择样式(ie不支持此属性)
<
link
rel
=
"
stylesheet
"
type
=
"
text/css
"
title

"
blue
"
href
=
"
dreamdublue.css
"
/>
<
link
rel
=
"
alternate stylesheet
"
type
=
"
text/css
"
title
=
"
red
"
href
=
"
dreamdured.css
"
/>
