Exercise _3_profile card component with much love <3

Hi guys, I managed to do this challenge but had a bit of trouble setting up the two background svg images. I initially tried to set the background with css but with poor results, I still left the commented code inside if you want to have a look so you can explain to me where I am going wrong.

I need advice to learn how to make my code more responsive. I think this is becoming more and more important. For this reason I need all your advice!

I also accept advice on position: relative; or position: absolute;

Thank you all, I love you <3
