Tailwind CSS: It looks awful, and it works

In his talk at Rails World, Tailwind CSS creator Adam Wathan explains why “separation of concerns” isn’t the right way to think about the relationship between HTML and CSS, why presentational class names lead to code that’s so much easier to maintain, as well as loads of tips, tricks, and best practices for getting the most out of Tailwind CSS.

I've been using Tailwind for years and still picked up some excellent tips from this talk and demo. I haven't used the group feature often, and the demo of css variables at the end was great.
