Flexbox , POSITION ABSOLUTE AND RELATIVE

Hello all ,

Could I get some feedback on this one even I wasn't able to deal with the background I'm pretty happy with the result on the desktop version but on tablet and mobile under 600~ pixels the design is completely broken. I haven't found the right way to crop the image like in the design on mobile version even I know that a property like object-fit can helped me and I think I used too many time the property position on many elements that haven't help too.

I thought I should have focused on the mobile version first

Thanks for reading !
