QR Card with HTML5, SASS, and BEM

Please, check my 'main' branch for the code.

• I'm pretty sure I failed in making the site accessible. I would love any feedback on accessibility, since it's something I haven't explored yet.
• If you go to my index.html, do you think I managed to follow the BEM naming convention? I would really like to incorporate it in my practice.
• As for the rest, I would appreciate any kind of feedback 😀.

PS: I'm aware this is a small project and setting up SASS took more time. But I feel like I can experiment more with smaller projects 😅.
