Grid Responsive QR Solution

What are you most proud of, and what would you do differently next time?

It's one of my first few projects to use both flex box and grid together even this time i added an extra flex-box to add a personal link.

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

The image fitting into the grid is really challenging for me overtime, the responsive design is also challenging to find the width that covers a decent design for each device.

What specific areas of your project would you like help with?

The image size of course, as you can see i dedicated only 3fr row for the image however, in responsive devices as you can see it exceeds the 3fr so much. i want to know how to force images to fit the grid not the opposite. Also the font was set by pixel and still it appears to be too small for some devices in responsive view.
