QR code component

Hello dyl25,

This is a really good solution. I would like to suggest that you use .container class on the main element instead of creating another element (div).

Also, wrap img in a container like 'image-container' class. This is required for uniform rendering on some versions of internet explorer. It is also considered a best practice.

img element must have attribute alt="description of the image". This is displayed if the image could not be loaded. However, if the image intended to be used just for design, empty string should be used instead. For example, <img src="my-image.png" alt="my profile picture"> or <img src="background-image.png" alt="">. This is also good for accessibility.

I hope you find it useful.
