<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
<script>

</script>
</head>
<body >
<a href="网址" onmouseover="hello()"> 网页名</a>
</body>
</html>

　　2、文本域显示内容,但不可修改

　　3、让select控件可以自定义边框

4、CSS圆角

<html xmlns:v>
<head>
<style>
v\:* {behavior: url(#default#VML);}
</style>
</head>
<body>
<v:RoundRect style="position:relative;width:200;height:100px">
<v:shadow on="T" type="single" color="#b3b3b3" offset="5px,5px"/>
<v:textbox style="font-size:12px">css实现真正的圆角表格</v:textbox>
</v:RoundRect>
</body>
</html>

　　5、建银密码输入器
