I managed to handle the grid functionality in more detail and in a way that is easy to understand for other developers (I hope :P).
What challenges did you encounter, and how did you overcome them?The grid dimension was quite large, I had to create several media queries between the size 1440px and 375px, in order to make an additional column appear each time the screen size increases. This allows to have pleasant content to read on a majority of screen sizes.
What specific areas of your project would you like help with?Any advice is welcome !
