Which brings us to the cynic's view. It has always been possible to include banner ads on Web pages without using frames, but frames make this task a great deal easier. Like them or not, though, frames represent an important part of Web publishing. The browser will ignore the frames information if it finds any of these first. Though of course, frames do contain standard HTML pages, on which the familiar rules still apply.
Frames make a difference.
By implication, frame layout pages constitute a new class of HTML documents, a more general and abstract level of structure that is connected to the older forms, yet distinct from them. In this respect frames were ahead of their time. If nothing else, learning about frames will broaden your Web publishing horizons. This is not particularly consistent, so notice the difference between tables and frames in this regard. Of course, you can write frame layouts having only columns or only rows.
