For a more complex approach to frame design, you can combine columns and rows to get the effect you're after. This is accomplished by nesting frameset elements (see Example 6-7).
<frameset rows="100, *"> <frame src=" /> <frameset cols="200, *"> <frame src=" /> <frame src="1" /> </frameset> </frameset>
This results in a row along the top with two columns beneath it (see Figure 6-5).
You can now try out numerous combinations. Again, we're using only dummy pages here, but you could see where this design might contain a masthead, the left column some navigation, and the right column the content.
