Seamless Responsive Layout with Flex and Positioning

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

I have designed this kind of layout for the first time and It made me think of how will I do that and what are the different approaches I can try? So I'm proud that I could design it.

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

Creating the layout for large devices as shown in the design was challenging for me. I first used grid but I couldn't make it using that and then I tried using flexbox , it was also a failure then I tried CSS positioning and flexbox together to make the design possible , it was also not easy but I finally did it.

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

I would like help in the section where I have designed the four card layout for large size because I have use css flex and positioning . However , I want to know can we make it with different approach like using grid.
