For those confused by the new Grid Block Manager in CS-cart 3, I found this article very helpful.

Once one understands the new Grid Paradigm the Block Manager makes more sense and creating a customized layout is much easier.
The design and layout is at your fingertips without changing any tpl code, just CSS modifications. Note the Block Manager GUI built into cs-cart does most of the CSS writing for you as you create your design.
Have Fun,
