I add to use fixed size for image, background and div, I'm not sûre this is the best option, if you have any tips I'd like to see that :)

Hello challenger !

I am very curious about the background solution, I'm not very good with numerous images in background and I'm pretty sure my solution is not the best at all, so I would really like to have a feedback on that part.

The card itself took me less than 30 minutes (and I reeeaaally took my time).

Tank you !
