Need to expand the slider that would fit the webpage

Sunday, May 4, 2014

I'm trying to expand the slider from both ends of the webpage.

Check this link

The problem is that, when I tried to expand it, it loses it's quality making it distorted looks also the below content, moves to the left. I was just thinking to add a blue background color on the slider just like the header and footer in that link.

Any help for this one?
