Three column card preview challenge

Hello! I just finished the challenge here provided, and now I am looking forward to the viewers feedbacks. I am sure this one I did really bad though

A thing which for sure was hard for me was element positioning. On the original design, you can see the card is far away from the paragraph when compared with the image, header and paragraphs gaps. I really think my approach to solve this problem without using min-height is not the correct way neither is it accessible. I don't really know though.

I am unsure about every part of my code, I think I did it really bad this time. If possible, I look forward to improve the accessibility and the responsiveness of my project, please.
