Responsive features grid with HTML and CSS

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

I like the final results and the way the widths of the cards, the whitespace and the typography adapts to the viewport size.

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

Specifying the values so that everything is responsive was challenging, especially in the case of margins and gaps. I used a lot of clamp()s and calc()s to solve this.

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

Although I am satisfied with the grid, I expect there would be some easier way to make the layout shifts work. I am open to any suggestions, tips & tricks.
