I understand that the main story is centered and sectioned but what if i want put a stat box to the side of the text to show readers how their attributes have changed based on their choices?
Is it possible to? And if yes, how please.

I don't think it is. If it is, I'd love to know how, too!

It can be done. You need to design a proper html&css layer container where the squify story goes in a div and the box in another div align to be side by side.
Then you need to pass the values via js from the story to the box et voilá!
