I used html and CSS grid layout tool

Hello People! I completed this project to improve my layout skills which I did up to some point but I ran into few problems, described below: 1- The first one is that the text in the right most card does not fill the empty space. I could not find any method to some how smaller the heights of all the cards EVENLY so that there's no empty space left (as shown in the design).

2- The 2nd one is about the 'media queries' and it looks like a bug to me. When I first wrote the media queries for mobile and tablet view they worked perfectly but later when I was fixing the above problem I may have edited something that caused those media queries to come into affect at all.

Any help would be appreciated. Thank you :)
