Figma hard coded pixel values for qr card

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

I am proud of learning how to use figma to get dimensions for the elements in the template. I would like to find a way to easily size the elements without copying the pixel values directly from figma

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

I was having challenges getting the right pixel values between elements but then I learned that you can inspect them using the alt key in Figma.

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

I would like to be able to use more libraries and frameworks but I am not sure what they do differently than raw css. I would also like to know if I should be using raw pixel values when using figma or just approximate them and use values like rem and em.
