I believe the answer you want to percentages (%). The "bummer" message tells us that and` are font-relatvie measurements so they measure the size of the font stack whereas for this scenario, percentages are used to measure the relative size of elements. So in this question the other question you referenced is correct but you're not concerned with em or rem at all. :-)
