change width of the widget

Hi, I have included a text widget at the bottom of the web. that I can do to make the banners stay on the edge of the screen? with the same width as the slider?

This is my web : http://inelga.org/

Could you mark change this on a screenshot?

Im not quite sure on what screen size you are testing the site, but if you will do it on big screen (like full HD), you will see, that putting those banners to the left of the browser window (disable centering column) will make layout looks very weird. The image above is centered also, only arrows are aligned to browser edges.
