Background Picture with Content Inside

Looking to use Foundry to create a site similar to this one. http://richterlandscape.com/ 2

I figure I could find a pre-made theme but want to try it myself. Could anyone inform me on how to layer the stacks? Or what stack I should look at getting to make this happen?

Foundry will allow you to set a background image for your site using the Foundry Control Center stack. In your example that would be the nice tree leaves in the background. You could use a Container stack and columns to build out that center piece of the site, along with a navigation bar for your menu.
