Site cutting off left side

Said website in question: http://cottonduckdesignstudio.com. I am goober new to any of this (Put it this way I know where to find the CSS, but I have NO idea
> what it means) so go easy on me with the jargon :).

Let get a few things out of the way:
I’m on a MAC Safari Snow Leopard
The last plugin I installed was MiniMax (and I love it)
I’ve located the custom CSS and I entered this: #content {overflow: visible;} according to another forum, that should have worked.

I keep trying to move the page like I’m in InDesign… yeah thats not working either 😉

ANY help would be MUCH appreciated!!
