It’s quite a nice site btw. But yeah you have both containers floating to the left.
It could be possibly the width you have for your #container. It’s set to 100%, have you tried removing it and seeing if that works? Or possibly re-ordering the containers?
It appears you need to check what you have as front display for your site. If you want the site to display a static page go to your admin panel.
Under Settings > Reading and change it to be one of your pages. Hope this helps. 🙂
