QR Code Component Challenge HTML/CSS

I'm very new to HTML and CSS and this was my first challenge outside of the course I've been taking on Udemy. So it took me a while to figure out where to begin and how to make everything look the way I wanted it to.

I had to take a break from this challenge as I got stuck fairly quickly. After returning I managed to change quite a bit. And though it's flawed, and not quite finished, I'm still proud of what I managed to do so far.

Feel free to tell me if there's things I should take another look at or if I should do certain things differently. Like I said, I'm very new to this and would rather learn to do things correctly now instead of in a couple of months!
