Hi, 

Is there a way to make this page https://www.celsodinizphoto.com/new-page behave like this https://www.celsodinizphoto.com/behind-the-scenes or like this https://www.celsodinizphoto.com/videobts/ in the sense of using the whole real state instead of being limited to the max width size allowed on the style set up?

Thanks!

Celso.
