Tutorial
Place this code on your content or department page to create an iframe to another page:
<frameset rows='100%, *' frameborder=no framespacing=0 border=0><br /><iframe src="http://www.otherpage.com"; name=mainwindow frameborder=no framespacing=0 marginheight=0 marginwidth=0></iframe><br /></frameset>
The widths and heights would have to be set to fit the page correctly on your site.
<iframe src ="html_intro.asp" width="100%" height="300"><br /><p>Your browser does not support iframes.</p><br /></iframe>
