o the next question is: How big do we want each column to be? We can size them either by percentage of the screen width or by a certain number of pixels, which are the tiny little dots that make up a computer screen. In this case, let's say that we really like chicken, and we want chicken.html to take up about two-thirds of the screen, leaving only one-third for the other portions.

Our frameset will look like this:

<frameset cols="66%,34%">

Now there are two columns. The first (or left-hand) column will take up 66 percent of the screen width (which is about two-thirds of the total width), and the second (or right-hand) column will take up the remaining 34 percent of the screen width. (Note: Percentage numbers are separated by a comma without any spaces, and the two numbers must add up to 100.)
