Basic Html and CSS

Hey everyone, this was my first submit here and probably my first frontend challenge.

I struggled a lot with some basics concepts and I think that I couldn't apply all that the challenge requested.

Appointing the worst part of my lack of knowledge, definetely was the necessity of setting "position: absolute" on the all Card properties. I really can't understand why that was required.

I'm very thankful for all possible feedback and I will revisit basic HTML and CSS concepts.
