今天是巩固的from表单跟嵌入其他页面，同样的，学习到了新的知识。
温故而知新：
iframe——在原页面嵌入其他页面，以窗口的样式
其中scrolling——滚动条
noresize——可调整大小
frame——边框线
瞅下练习的代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>
<body>
<iframeset rows="200,*">
<iframe src="http://www.baidu.com" scrolling="no" noresize"" ></iframe>
<iframe src="http://www.hao360.com"></iframe> </frameset>
</body>
</html>
