Profile Card Component using HTML and Sass

I really enjoyed building this project, this seems simple but there were lot to learn, So placing given background images, I face some difficulties determining their positions, I use background image related properties like background-size, background-position etc... however when designing mobile view again I had to face the same issue because background images moved over each, so then I had to reposition and resize the background images again, so fellow developers is there any good practice other than what I have done here. please your review will definitely help me to grow as a developer, thank you very much.
