There are a few things remaining worth mentioning. First of all, what about all those people with browsers which do not support frames? Well, Netscape found an elegant solution to that. Unknown tags get ignored by browsers, so the tags <frameset> and <frame> won't show. However text in-between tags is shown. So, they added a <noframes> tag pair to display an alternative content, not unlike the ALT element in the <img> tag.

Often, only one frame carries vital information, whereas the other frames are peripheral and only help with orientation and navigation. In these cases it would be possible to store the content additionally in the <noframes> section. This has an obvious disadvantage that content needs to be kept in sync in two locations (files). Therefore one of the standard procedures is to only link from the <noframes> section to the document with the main information: 

<html>
<head>
<title>Standard</title>
</head>

<frameset cols="20%,80%">
	<frame src="sidebar.html">
	<frame src="main.html">
</frameset>

<noframes>
	Since your browser can't handle frames, please jump to our 
	<a href="main.html">main information page</a>.
</noframes>

</html>

There some more tag elements that I haven't mentioned, but since this is the Internet, there's really no point in listing them when Netscape has an excellent syntax definition for them online.
