axe-core, nested styling

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

It's not a "proud of situation".. I almost finished the "news-homepage" but didn't commit my solutions though, since I felt lost on the responsiveness ! So, I started from again from the learning paths, and this "qr-code-component" is the first challenge I need to solve in order to proceed to next one.

I look forward to learn the responsive design, once and for all.

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

There's no real challenge, but I didn't previously learn to align to center, elements without flex ! so, I used "margin: auto".. that's a nice trick.

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

Maybe It's too soon to recommend something to someone, but I think it's similar to a boilerplate code for making components, in next projects.
