Netscape invented "the feature" called
Frames.
Frames divide the Browser Window
into functional Panes (Like the Mail
Window).
The Frame (Panes) are (currently) difficult for the casual user to create..., but very "easy and convenient" for you to use. There are a few differences that you must know about in order to get around in a Web Site using Frames .
The Frame on the left acts as an Outline, and the Frame on the Right acts as the Viewer. You simply "click-on" the Outline on the Left..., to produce the Information on the Right!
