12.1 Title each frame

Each frame should have a title, even though browsers don't display the title. Use the title attribute with the <frame> tag to describe the content of the frame. This allows users who are not able to access multiple frames simultaneously to pick which frame to look at.

Treat frame titles like link titles and make sure that they have names that provide a good idea about the content of the frame. For example:

<frameset rows="10%, 90%" title="Anite Public Sector web site">
<frame src="navigation.html" title="Navigation bar">
<frame src="content.html" title="Main Content">
</frameset>

If you do use frames, use the <noframes> attribute to provide an alternative for browsers that can’t handle frames.
