I have four pages: index.htm top_frame.htm middle_frame.htm bottom_frame.htm
Then the code of index.htm is as follows:
"http://www.w3.org/TR/html4/loose.dtd">
Add closing tag
<frame src="top_frame.htm"></frame><frame src="middle_frame.htm"></frame> <frame src="bottom_frame.htm"></frame>
Add Still doesn't work!
"http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>无标题文档 </title> </head> <frameset rows="30%,50%,20%" border="0" framespacing="0" frameborder="0"> <frame src="top_frame.htm" marginWidth=0 marginHeight=0 frameBorder=no noResize > <frame src="middle_frame.htm" marginWidth=0 marginHeight=0 frameBorder=no noResize > <frame src="bottom_frame.htm" marginWidth=0 marginHeight=0 frameBorder=no noResize > </frameset> <noframes> <body bgcolor="#FFFFFF"> <table width="100" border="4" align="left" cellpadding="10" cellspacing="2" height="100%"> <tr> <td> <p align="center"> <font color="#0000FF">浏览器功能支持限制</font></p> <p>     非常抱歉，您的浏览器不支持框架模式，无法使用本模块，请使用支持框架的浏览器。</p> <p> <font color="#FF0000">*</font> <font color="#000099">建议使用 Internet Explorer 6.0 或版本更高的浏览器使用本模块。</font></p> </td> </tr> </table> </body></noframes></html>

I'll tell you the reason, just change the browser and it will work! ! Some browsers do not support frames, such as 360
