skeleton + twig + laravel = no complaints.

I actively dislike 960, and instead prefer Skeleton[1] which does the same thing as 960 but (in my opinion) better and more cleanly.

The only major difference is syntax, though skeleton's approach is more semantically correct. Before you try it and start complaining though, I have no idea if it will center how you like.
