My point isn't that Tailwind should've used CSS variables in 2017, it's that technology from 2017 isn't very compelling in 2020.

> I love though that as an engineer you would be hesitant to use Tailwind, but you are not aware of how new variables are.

Why would you think I'm unaware? Please see: https://caniuse.com/#feat=css-variables

I'm not writing software for IE 11 (released in 2013), Opera Mini, QQ, or Baidu, so CSS variables are widely supported for my target demographic.
