SASS, Grid, FlexBox, JS, Parcel

Well, one hell of a battle for me. I had overflow on my grid and "minmax" and other options which I tried didn't work. The chess picture was tricky as well. The solution is close to design just because I've used many too many @media queries. I hope to read some of your ideas and feedback. Feel free to point out all of my mistakes and downfalls. Maby it won't hurt me that much :) I used Sass for the first time and I love it. But deployment using Parcel for the first time was heartbreaking. It took a few days to solve the issue. My 'senior' friend helped me. Big Thanks to (https://pawelgrzybek.com/). This guy is an Alien. Follow him and you won't get lost. In JS I've used forEach() and for loop to practice two different ways. Happy New Year !!!!
