[SOLVED] montezuma not displaying properly on iphone

hello,

when i look at the montezuma theme on my iPhone, there is a ~20px margin on the right side of the entire content container. is there a way to get rid of that so that it displays full width on the phone?

i found these two threads that have the similar problem
Breadcrumbs - Not 100% width when loaded on iPhone

[SOLVED] Front Page width on mobile

but i couldn't figure it out. here's a screenshot, i colored it so i can see the edges of the boxes.



much thanks.
