I am the one that created the site, Layout Cookbook, including the designs, and the layouts. I apologize if the name was misleading. The term “cookbook” in this sense comes from a designer’s point of view, not a programmer’s point of view. The design elements of the layouts are the ingredients, you mix-n-match them together to develop your own layout. (Rather than a programming how-to book where you are given code to develop the layouts.)

It is based on another great book called “Graphic Design Cookbook: Mix and Match Recipes for Faster, Better Layouts”, which is a book of illustrations for graphic design artists, available from Amazon.com.
