Is it typical for a frame src page to not apply the CSS that is referenced in the container page?
For instance, if the external style sheet defines an id #divbody that specifies the text color, and Header.aspx contains a div with the id divbody.
<!DOCTYPE html>
<html>
<head>
<title></title>
<link href="StyleSheet.css" rel="stylesheet" type="text/css" />
</head>
<frameset rows="25%,*,25%">
<frame src="Header.aspx" />
<frame src="Body.aspx" />
<frame src="Footer.aspx" />
</frameset>
</html>
