Notes for Reviewers

This is how the responsiveness looks currently. I think this looks too crammed, and long in height. Should we consider separating the information into several panels?
Also, for this I cannot rely on our screen breakpoints, because there is a medium screen where the panels are in a 2/2 grid, and need to have the responsiveness applied, but then right after, on an even smaller screen the panels are already in a 1/1 grid and there they don't need the responsiveness. So I am using container media queries. We should define container breakpoints, because right now I am using the width of the moment the layout breaks.
