As part of the learning track on responsive design, Frontend Mentor is requiring me to give feedback on someone's work, and they chose you, so that's why I'm "critiquing" your work. :) - I had a whole lot of trouble when I did this challenge, so I only have a couple of small things to offer. 1) when I re-size to view your mobile layout, it doesn't show up - did you not do a mobile layout? and 2) if you need some help with grid, I'm going through a course right now that I highly recommend. It's by Wes Bos - https://courses.wesbos.com - and is a good tutorial to follow along with. It has helped me understand several things better (so far - I haven't finished it yet). Keep up the good work.
