If you will compare two Letterpress installations:
J2.5 http://walnutforkalpines.com/alpine-25/
J3.2 http://holmwoodgoatfarm.com/hw/ (under development)
you will see that in 3.2 the spacing of content and modules butts up against the edge of the page rather than being spaced away from the edge as in the 2.5 site. If you click on the link to "Senior Does" or any of the articles in that category list on each site you can really see the difference.
I had the same problem with a few other templates. I wanted to use Nocturne for the J3.0 site but everything, modules and content, butted up against the outside edge. No border all the way around as you see in your demo Example Style #3. Sorry, I don't have a site using Nocturne for you to look at. I should have contacted you earlier while it was still up.
Thank you for any suggestions you can give me.
