Discussion on: Do you use a CSS framework based on CSS Grid?

Sure! Grid is IMHO the best change to CSS in like a decade, so definitely try it out! Here are some of my favorite Grid resources:

• "Basics of CSS Grid: The Big Picture" by Jen Simmons, as well as the rest of her CSS Grid videos
• Grid By Example - Rachel Andrew
• Just in general, any talk on Grid (or really anything else) by either Jen Simmons or Rachel Andrew is guaranteed gold standard material
• Grid Garden, a little interactive tutorial/game that teaches you the basics of how Grid works
• If I might shamelessly plug for a second, after you go through Grid Garden, check out the article I wrote on Grid Areas, which are my favorite feature of CSS Grid Layout Level 1: CSS Grid Areas are amazing
