Infoway Theme: Feature Box aligned to left, want 100% width

Hey,

I want to make the feature box stretch to 10% of the page width. Currently it appears to be aligned to the left. I have set the widget that normally displays to the right of the feature box to “none” using some css styling if that makes a difference.

Here is the website: http://perimetercontrol.ie/

you can clearly see the feature box just under the main banner image. It is separated into three columns which is fine for me, I just want them to occupy 100% of the space.

Any help is appreciated.

Tommy
