我的做法是：假如你所说的那段文字放在一个DIV里，DIV的class属性就是定义DIV容器里的元素的样式的，id就是给javascript获取到该元素的。获取到之后通过改class属性，就相当于改了div里的样式
<html>
<head>
<style type="text/css">
.style1{font-size:12pxfont-weight:blodcolor:red}
.style2{font-size:14pxfont-weight:blodcolor:blue}
</style>
<script language="javascript" type="text/javascript">
function change(){
document.getElementById("myword").className= "style2"
}
</script>
</head>
<body>
<div><a href="#" class="style1" id="myword" onclick="change()">我是DIV里的文字</a></div>
</body>
</html>
