Do you find those light-on-black code blocks in dark-on-white context OK? I know nowadays it's almost a "standard": dark colour scheme for coding environment is truly widespread (mostly I stick to it myself) but on /bright/ page about typography it feels weird: I thought typography relies on visual balance and 'airiness', and seeing super heavy black rectangles on page promoting good typography is … strange. (I generally consider alternating bright and dark blocks in same page really bad design choice, because it produces aggressive contrast switches putting unnecessary strain on my eyes, but is seems it's just my deficiency.)
