QR Code Component using Sass

Good work!

If you want to improve the responsive design, there is a nice technique:

1. Images become responsive by adding: max-width: 100%; With this CSS declaration, width and height can be omitted. Now the image will scale automatically.

2. Currently, width: 320px; is applied to the card. By changing it to max-width: 320px;, the card will automatically shrink on small screen sizes to prevent overflow.

I hope that's a bit useful.
