edit content width

I have created a new website using this awesome theme, and it is coming along great. However, on a page (not the title page) I would like to edit the width of my content. I am not using any sidebars, so there is enough space for me to scale my images and text better. Does anyone know how to do this? I was thinking of a simple css. this is conerning my third, fourth and fifth rows.
