Cancellation of edges

Hello, I need advice on how to cancel the edge of the site. I can not find it anywhere. Thank you

Anytime you are looking for css stuff I always recommend firebug. I've got it installed in both firefox and chrome.

Chrome:

Firefox:

Thank you for your reply. At night, I figured it out. Now I'm running without problems. You have made a nice site.
