A responsive QR code component

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

I'm most proud of just simply starting this project, and most particularly this platform. Although I've known about it for a really long time, I'm just starting this now. As for this particular component, I'm proud of making it, within my estimated time range.

As for the next time onwards, I'll draw a rough wireframe of the component/site before its coding. Coz this time, I had a little rough start coz of not doing it.

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

As it was the 1st challenge, this one wasn't hard per say. But as I mentioned earlier, I had a little rough start coz of not making the rough wireframe before going on with the code part.

I overcame this challenge by screenshooting the desktop version design and then using it for reference, multiple times.

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

I would appreciate reviews and feedback on my code, like the better/shorter/more efficient method for the functionality, and regarding the responsive part of my design as well.
