Here’s the JSFiddle (disregard the differences with picture below):

I’m supposed to have something like this in the white background, but the images in the center and right column seem to expand outside of their domain.

Any suggestions on how to cleanly handle this situation? It needs to be nice and centered, needs to end up like the picture, I feel I’m close but can’t quite get there. Thank you, learning quite a lot in this tag area in Stackoverflow.
Use pixel widths, not percentage.
