By default, the x-cart templates expand to the full size of your computer display settings. Therefore the table in which the categories are displayed expands to fit as well, leaving a lot of space between your category images.
In order to maintain consistent size viewable on most system settings, we generally set the width of the entire site to 760 pixels. This will allow you to left justify or center your cart also.
For example:
http://www.uneedabirkenstock.com
This site is left justified as well as using the 3 column category layout.
To do this, modify the rectangle_top.tpl
from this:
Code:
<TABLE align=center border=0 cellPadding=0 cellSpacing=0 width="100%" height="100%">
to this:
Code:
<TABLE align=center border=0 bgcolor="#FFFFFF" cellPadding=0 cellSpacing=0 width="760" bordercolor="#000000">
Depending on which version you are using there may be 2 instances of this table. (One for the customer end, and one for the administration section.)
I hope this helps...
