lightbox opens off screen

I'm using slimbox 2, a lightbox that is jquery based. It works ok in Coda locally on my copmputer but when I upload to the web, the lightbox opens to the right of the screen (mostly off to the side of the screen). This has happened with a couple different lightbox scripts I've tried. I am not sure what the conflict is in my css that is causing this.

Here is the site (http://www.brianzeiders.com/#1)...

any help is much appreciated.
