@matigo I was just about to post that a little inspection discovered why it was overlapping. I don't run my Safari full-screen, there is a slight bit of background windows on both right and left (for reasons) so your 8.33% computes to only 57px for the bounding box, and the 70px images overflow into the body text ever so slightly. If I drag Safari to the sides just a nudge there becomes a buffer. If I collapse Safari slightly it reformats to a different layout entirely. Seems I'm just a problem child with my browser size (looks like roughly 1300px wide, according to the dimensions of the 'banner' element).
