Move Sidebar From Right To Left Help

I’m using the theme VideographEx 1.3 by Emiliano Bruni and one of the sidebars(sidebar3.php or also referred to as sidebarright) is all the way to the right so how can I move it all the way to the left and also move all the posts into the center? I will post the code for the Stylesheet below(Hopefully that’s the right thing to do lol), the website to see the preview of it is also in the code below so you guys can see what I’m talking about. New to wordpress so any help is appreciated, thanks.
