zen cart 1.3.8
not upgraded.
added column layout grid.


building a webstore..keeping it really simple. finding as much as i can without having to ask, but here it is..


1. implementing my html header into tpl_header.php and my logo won't stay on a left alignment. it floats around when you expand the window.

i'm trying to match http://www.decepdesign.com/home.html


2. i've got my individual products centered on the page, but i'd like them to float (is that the right term) so if you expand or contract the page they stay centered (with the menu).

3. I'm trying to find a way to keep the center column a fixed with, but float so the whole center column will always be centered, adjusting as you expand or contract the window. I followed a thread to fix the width, but it's in a fixed position.
