It is the sample layout from the pure css site converted for GetSimple. Fully responsive for any screen size. The menu and title block stays put while the page is scrolled up and down, (except on phones). Doesn't need to be a blog. would make a good site. The original page is at: http://purecss.io/layouts/blog/.
It's a normal theme.
I left in a fair bit of stuff which will need deleting or adapting for use with a GetSimple plugin like News Manager (Updated) but it shouldn't be too hard. Ask on the forum if you don't know how.
