Is your feature request related to a problem? Please describe.

hello guys, thanks for your delivering all the stuff, but after v2.0.0 space unit changes from px to rem, rem calculations is base ROOT_FONT_SIZE = 16px, but my project is base on 10px, so can we provide config to change ROOT_FONT_SIZE, i think is's useful for many people

Describe the solution you'd like

rem calculations base on real html font size or config ROOT_FONT_SIZE Instead of fixed number 16

Describe alternatives you've considered

i think add config to change ROOT_FONT_SIZE in tailwind.config.js is a better choice
