All solutions

Not too sure if I did it the right way, was I meant to use html to switch the images and add alt tags or is putting it in css good enough? I don't exactly know how to get around putting alt text for background images. Any feedback is greatly appreciated.

I tried building this QR component but had trouble getting it perfectly responsive across all screens. I ended up using media queries, alongside clamp, but is there a better way I could have done this? I feel as though I am using clamp incorrectly. Any other feedback is of course greatly appreciated.
