Simple Calculator with Three Themes Using Flexbox and Grid Layout

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

I have no experience with most of the works I did in this challange and I learned a lot. I am proud of myself next time I will use responsive and relative units such as: clamp.

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

I tried to make the layout of the number keys using flex box and things didn't go well for me because everything needs calculation. But I finally I used AI tool and stackoverflow and findout the Grid!

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

As the screen get larger and larger the border-radius which is currently fixed (10px) will be very small and the edge won't be curve. when i use % instead of pixel for border radius it does not make it curve or circular rather it makes it eliptical. why is this happening?
