QR code Component

The only thing I can see is that the drop shadow seems to be missing from the main white box. Otherwise this is literally pixel perfect. This is definitely the best solution I've seen so far. Well done!

Your solution is perfect, you've really done an excellent job well done! As a suggestion though to make the component responsive even on a higher range of devices and to make your width more reliable, I just thought it would be better to use the max-width property instead of width for the component because it reduces the lines in the long run and many other benefits concerning responsiveness. Otherwise, Seriously you've done extremely well. Keep up with the code.

The component code used to create the QR code would have been carefully designed and tested to ensure that it meets all of these requirements and functions as intended. This involved several factors such as encoding of the data, the size and layout of the code, and the error correction level used were visible in the code.
