I am not sure of the best way of approaching the background images in this case. I attempted to use VW units to make it responsive, but this seems to be not correct as the screen size changes it will not react as I expected. Any suggestion would be appreciated here.

I would be glad to any advice for mobile-first approach :) Any suggestions you might have! Any comments!

I would like your Feedback, to correct something that is messy or wrong in my code and to have a different point of view to aggregate in my knowledge. Thank you in advance. 🙏🙏🙏
