The background is comprised of two images, a looping wallpaper and a painting overlaying it, which may vary for certain pages. Is it lazy? Yes! Does it work? Yes! That way I don’t have to worry about arranging <div>s in rows and columns, I just give them absolute margin-top and margin-left offsets.
I went for a site design that was 800px wide so that it could display attractively even on phones (landscape orientation). The font sizes are not in em or vw, but px.
I like these things, nonsexually, I think they’re cool. Gives the site a lived-in feeling, you know?
