Creating QR Code using HTML, CSS and JavaScript

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

I learned the usefulness of transparency in color.

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

I faced the challenge of including inner circles behind the QR code. Initially, the circles overshadowed the parent element. I tried adjusting the z-index, but it didn't achieve the desired effect. Then, I decided to set the background-color of the circles elements to 'transparent'. This helped to hide the overshadow.

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

I would like to get a feedback as regards the code and accessibility.
