It seems to me that Pollen CSS allows you to build BEM approach CSS files that use the good ideas from Tailwind (well-defined standard-definitions that can be changed easily at the root), since it’s all based on CSS custom properties (“variables”).

I still find it hard to use libraries like tailwind and such, I prefer a more fully BEM approach where elements are important based on their location in their parents or by what specific selector they are. Using selector names like grid-12 or whatever feels way way too much like putting the presentation data in the html directly instead of just properly linking it…
