I had finished this website a while ago but something happened to it and I've now spent all day fixing it and getting it back from scratch as my backup wasn't correctly done. I don't quite understand what it's doing as I've done this technique on many other websites with no troubles, maybe I've looked at this website too long?

Here is the website. I'm wanting to put some space on the left and right hand side, however I dont just have one container as I was needing the dark grey bar at 100% of the screen and always under the banner no matter where it was. So there are 4 "containing" divs that I want to have the space. I've placed soem CSS3 media queries in but now I'm getting a gap to the right. I was thinking it was because my background mages are going all the way across but they set at 100% so I'm just not understanding whats going on. It's somethign simple, I'm not seeing it right now..

This is what I have for the media queries

/* Smartphones (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) {

#header, #banner, #main, #footer-widget-area { padding: 0 2em 0 2em; }

}

This is what t looks like on my iPhone

Any advice is helpful and appreciated.
