Centering magazine when enlarging

[mlopez1007]

Hello -

As of right now my width and height properties with the turn.js basic are 922 and 600 respectively.
When I preview that page, the page is properly centered.
I want to resize it to 1229 by 800. However, when I do that, the magazine isn't centered.
The auto center property doesn't help.

Where else can I set the centering after enlarging the element?

Disregard, I was able to find the parameters for this.
