QR Code Using Flexbox

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

I'm proud of deploying my first website using Github.

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

Matching the design's measurements was not straight forward. I used trial and error to approximate the solution.

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

I'm not planning on using Figma. Are there tools or ways to measure margin, letter spacing, etc... from the design images?

I would also appreciate some feedback on mistakes I might have and what can I do to improve my code?
