You must have at least Netscape 2.0 to view Web pages using frames. If you're still using Netscape 1.1, you will not be able to view sites that have been enhanced by frames. Instead, you'll only be able to view that which the site developer has created specifically for non-Netscape 2.0 or 2.01 users.
Frames allow Web site developers to present information in more useful and flexible ways.
Some frames' content can remain fixed, like title banners, logos, table of contents, or navigational buttons, while adjoining frames are continually redrawing and updating content, like articles, query results, and graphics files. The very best way to understand what frames are all about is to look at sites that use them. Here at SDSC, SDSCwire and some of the staff homepages use frames. Additionally, Netscape has created a list of sites that use frames and is a good starting place for people interested in learning to use frames. Its important to note that not all frames are alike.
