color change on content border

I'd like to make the entire content box (of an individual page) the same color as the background content itself. I've been able to change the background color of the content pane using: #post-34 .entry-content {background-color: #61c7f2 !important;} But I can't figure out how to apply that to the entire border as well http://thepowerofwater.net/share/why/
