This is an example of using two frames. A thin frame along the left margin that acts as a static navigation menu throughout the Web site. The second frame, which often isn’t even thought of as a frame because it takes the majority of the screen, is what some might call the “content window.” It is the frame in which all information in this Web site is displayed.
This is another example of a static navigation frame. Each cell in this frame is a hyperlink that will bring a Web page up in the larger frame above it.
