Responsive page "Four card section"

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

I'm proud that i completed this task using display: grid; and made a responsive page

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

The hardest thing for me is Display: grid , but every time i'm try to learn something new

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

i think a good hint would be if someone suggested me a good video about display:grid so that i could definitely figure it out( in English, German, Ukrainian, Russian)
