Hello, Frontend Mentor community! This is my solution to the QR code component.
I have read all the feedback on this project and improved my code. Due to the fact that I published this project very long ago, I am no longer updating it and changing its status to Public Archive on my Github.
You are still free to download or use the code for reference in your projects but I longer update it or accept any feedback.
There are couple things to mention. You can use section tag instead of div for the info-block for semantics purpose! You also can add box-sizing: border-box to * because this tells browser to included margin and padding for the box. here Lastly, you can use caniuse check to see if the browser support certain CSS properties, ie: box-shadow in this case!.
It looks good. However for the testimonial part, you should wrap them with section tag for semantics purpose. You also have 3 accessibility issues, you may want to look into them for improvement purpose. Otherwise, good job! :-)
