Making widget backgrounds span the page

Greetings!

I am fairly new to wordpress, and am in the beginning stages of setting up my website, http://www.danryancreative.com

I cannot figure out how to get my widgets to span the width of the window. Currently its only a percentage and leaves uncomfortable gaps

Hello there,

Edit your page, and then open row options where you wish the widgets inside it to be expanded by clicking the wrench icon. In the Row Styles section, open the Layout tab. And then on the Row Layout dropdown, select Full Width Stretched.
