<link rel="stylesheet" type="text/css" href="mystyle.css" />
</head>2.内部样式表 当单个文档需要特殊的样式时,就应该使用内部样式表。你可以使用 <style>标签在文档头部定义内部样式表,就像这样:<head>
<style type="text/css">
hr {color: sienna}
p {margin-left: 20px}
body {background-image: url("images/back40.gif")}
</style>
</head>
3.内联样式由于要将表现和内容混杂在一起,内联样式会损失掉样式表的许多优势。请慎用这种方法,例如当样式仅需要在一个元素上应用一次时。<p style="color: siennamargin-left: 20px">
This is a paragraph

把这些代码复制到html文件里看看吧,要解释起码要几万字,打不了那么多。你自己慢慢研究一下,很容易看懂
