Responsive Four Card Section

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

I would do different the "shadow" of the card boxes

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

I didn't know why the cards on mobile look bad then I inspect the page and I saw bootstrap give to the row a left margin and I use ChatGPT to ask how to put the first paragraph like how it views in the design img (inline-block and width)

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

I would like to know if I use well the box shadow or it is another css property that makes that little "shadow" looks down and right of the cards
