How to Scale Your Media Queries

REM's is all based on the HTML tag font size. So it doesn't do any of this multiplying. It stands for root M's. And that's exactly what I do: I set the font size to be 10 PX. On my HTML tag. Then I always know that if I need something to be 20 pixels, I set it to two REMs and I sort of set it the reason why I set it as 10 PXs so that to maintain my sanity in terms of trying to convert over at the end of the day.
