Responsive Card Columns Layout with CSS Grid and Subgrid

What are you most proud of, and what would you do differently next time?

I am proud of being able to complete this challenge pretty quickly and also with getting more comfortable with CSS Grid and Subgrid.

What challenges did you encounter, and how did you overcome them?

I initially had the challenge with dealing the responsiveness of CSS Grid and Subgrid, when I finished the setup, I found that the card components didn't wrap. How I overcame that was to use the span keyword followed by the amount of rows created by the browser. See code below:

.columns__card {
  display: grid; 
  grid-template-rows: subgrid; 
  grid-row: span 4; 
}
