What are the best learning resources for Sass, Compass, and Blueprint CSS frameworks beyond GitHub documentation?

I’m trying to learn more about CSS frameworks and focus on Sass, Compass, and Blueprint. I’ve seen their GitHub wikis, but I’m looking for richer learning materials.

Can anyone suggest tutorials, blogs, or documentation that offer deeper insights into these frameworks? I’m also curious if there are other noteworthy CSS frameworks that I should explore alongside these three.

It would be great to get recommendations for books, online courses, or community forums too, as I want to ensure I’m aware of all vital CSS frameworks or learning resources.

yeah, blueprint’s kinda old news now! look into YouTube for sass tutorials, they r pretty useful. Codecademy also has decent stuff. and honestly, i think u should also try tailwind css, it’s taking off more than compass these days.
