QR code card

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

I have to confess that this apparently simple task is full of challenges for me.

For the color of paragraph ("Scan the QR code..."), I applied HSL color code specified in the style guide. But somehow, it looked much much paler compared to the sample design. Was something wrong with my browser...? I checked and double-checked everything I could think of, but couldn't figure out why. Finally I gave up and chose my own gray instead (Cheat!).

Also, I struggled with GitHub as always. Of course, I cannot use the command line, which is more than I can chew. Somehow, my css file wasn't applied to the html.index on GitHub. No matter how many times I deployed, it only showed an ugly html-only page... I almost gave up and deleted my repo. Then, I decided to create new repo and uploaded the files again. Somehow, it worked this time. This is the complete mystery for someone with my current skill and knowledge.
