Hello everybody!

I just completed the Frontend Mentor challenge and would like feedback on my project. Here are some specific questions:

1. What were the most challenging aspects when building the project? Was any specific part of the code harder to implement?
2. I'm using a list of objects approach to get the information dynamically. Do you have any suggestions on how I can improve this implementation?
3. I would like feedback on the structure of my code. Are there any specific areas I can improve in terms of organization or best practices?
4. I have questions about accessibility best practices. Did you notice any points where I could improve the accessibility of my project?

Thank you in advance for any feedback and suggestions you guys may provide. It will help me learn and improve my development skills.

Thanks!
