F is for Frames
<frame> & <frameset>
Frames seem to have had their day. For a time they were the thing
to do, but that time seems to have past.
But what is a frame?
A frame is a window in your webpage which can independently display
an HTML document. A frameset is a group of such frames. So your webpage
in your browser window is made up of a set of frames.
Frames is a different way to doing things, and I leave them alone,
since it's all too easy to do them badly.
