"Creating a new template for Zen Cart is fun. Prior to version
1.3.x of Zen Cart, some HTML tables were used for layout. But in
version 1.3.x onwards, Zen Cart has fully abandoned the use of HTML
tables for layout, using a CSS-based layout instead. This
step-by-step guide enables you to change the text and graphics
displayed in the front-end, customize the look and feel by editing
files, understand and apply the template override system, modify
and create new templates, and finally modify email templates.It
will help you make the shop more attractive with the new
templates."
