The Power of Three

I often remember the way to build a frame-based page by thinking in threes. To create a single-frame page, you need three documents, at the minimum. What's more, you use three unique bits of HTML that are unused anywhere else in the language.

Frames are controlled by a master document known as a frameset. The frameset document is not displayed in the browser in and of itself, but it sets up all the controls for the resulting page.

Along with the frameset document, you need at least two HTML documents of content. These are displayed in the framed areas created by the frameset (see Figure 6-1).
