Page responsive with CSS Grid, Flexbox and interative with JavaScript

What are you most proud of, and what would you do differently next time?

I'm proud to have made my first project with javascript, I think the code didn't look good, but it's functional at the moment

What challenges did you encounter, and how did you overcome them?

I found it very difficult to make the sharing container, I don't think it was good, but I managed to make it work properly.

What specific areas of your project would you like help with?

For now I would like you guys to test it and give me an honest opinion and help me improve.
