@todd Super WCAG-nit-picky here you need to test what it does at 320px viewport width to determine 1.4.10 failure (or 1280 at 400% zoom). WCAG says only that “a mechanism” needs to be provided and I have seen overlays break the layout but regular responsive layout working. So in that case there is “a mechanism”, it just is not the obvious mechanism that they shove in your face. /cc @marjon
