Responsive Product Preview Card Component

I'm still learning the technical terms and how to communicate better.

I completed this challenge using flexbox. I would appreciate feedback on a better solution on how to make and position the card component. I'm also learning a mobile-first approach and would like anyone to share any tip or their workflow. I had faced some challenges with this approach and although there was not a major change in the layout after completing the desktop layout, it would be helpful to know a better workflow.

Thank you!
