Center slider

I’m attempting to center the slider on my page. I thought I managed to get it centered using “more vslider options>container margin” however when you view it on a different computer its not centered at all.

Is there not a simple code that I can wrap <?php if(function_exists(‘vslider’)){ vslider(‘vslider_options’); } ?> with?
