Responsive Layout using CSS Grid and Flex

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

I've been getting more comfortable using box-shadow as I try to implement it. I put in a lot of effort to make the responsive design smooth, and I think it turned out well.

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

Since I'm not yet familiar with using Grid, I struggled a bit when initially planning the layout. Additionally, I wasn't sure how to specify the sizes of the elements, so I ended up implementing it somewhat haphazardly, which is a bit disappointing.

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

I would like to know how to specify the sizes of elements effectively when implementing a layout like this. Additionally, I want to write the code in a clean and efficient manner.
