下面就是一个简单的css定义：
<html><head>
<meta http-equiv="Content-Type" content="text/html charset=gb2312" />
<title></title>
<style>
.abc{width:500pxheight:30pxline-height:30pxtext-align:centerborder:1px solid #cccfont-size:13pxcolor:redmargin:auto}
</style>
</head>
<body>
<div class="abc">文字文字</div>
</body>
</html>
<style></style>之间写css代码。
.abc{这里面是定义abc的css}
<div class="abc">文字文字</div>这个class="abc" 就代表这个div的class是abc。css中定义abc就可以了。
