[SOLVED] How to shrink the theme?
 

I want to compact/shrink the side bars and the center content area
so that there is some empty space on the right and left sides like for example this page http://www.tizag.com/cssT/padding.php or you can take the example of this forum page, there is lots of Grey area on both right and left side

what value do I change for that?

Set the layout with to a percentage -see ato->Style & configure layout->layout WIDTH and type (fixed or fluid)

thanks it worked
