Abstract:

Frames have been controversial since they were introduced. To decide when and how to use frames, you must understand the technical details of how they work, and the arguments that have been made against their use. From a design viewpoint, there are at least two valid uses of frames: integrated into the page design of a single page, to provide separate areas for material such as navigation; as the mechanism for associating material from a specific author (such as comments) with other pages that normally stand on their own.
