QR code component CSS Flexbox

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

There really isn't much to this but if forced to pick something I think I would be most proud of actually completing and submitting it, finding answers to small problems with out falling down a rabbit hole of youtube videos and google searchs.

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

Proper coding conventions for organising and structuring my css.

This was a fairly simple project and the only real challenge I encountered was trying to center the element vertically, something I never really found the answer too, I think the way I have organised my flex containers is the culprit for this.

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

Any resources for the workflow of code organisation.

I believe I know what I need to look at next to improve. My foundational understanding of flexbox is lacking; revisiting and refreshing my knowledge will be my next step.

More than happy to receive any suggestions of resources there is appreciated but I'm sure a few searches will get me there.
