Product preview card component solution

This my first project after finishing the css and flexbox section of my course. I believe using position as much as I did led to more code then needed and issues I had to correct specifically on the mobile preview because of my reliance on position so it became a lot of problem solving issues I thought previous of as solutions. I think my footer would be a good example of that. So I saw this as an oppertunity to get through it and simply gain more awareness starting the next project that is similar to this one.

Any tipps and feedback is appreaciated. Thanks.
