There is a little problem with the background image of the wrapper which doesn’t fit correctly, it overflows on the right (on Mac Safari). My guess is that you’ll be struggling for a while.
Why don’t you remove this image and use a Css solution by setting your Div=”site_content”, a width (around 817 px) and a box shadow (right and left).
But doing that, i will have the problem i had .. I wont be able to make the site content look like 100% .. and as you can see, now it appear to be.
If i do that, i will have to remove the background center from wrapper, to put in the site_content and add that shadow, and i wont be able to put the site content looks like 100%
