Four card feature section

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

Pretty happy with my understanding of grid now. I was a bit lazy and completely disregarded how text wrapping was for the header section of the problem. I'll definitely convert the px values to relative units for future solutions.

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

The little color border-top thing was a bit difficult to think of. I tried using pseudo elements for this, but I don't know if this approach is the most efficient. CSS was also a bit messy.

What specific areas of your project would you like help with?

I think my use of media queries for responsive design still needs work. I need to practice media queries for a larger range of sizes for projects outside FEM.

Any critiques would be greatly appreciated as well!
