Responsive comments section using css grid and reactjs

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

I'm proud to have achieve the final result with the key functionalities working as expected. In the next time I would use a css lib to have a code a little bit more organized.

Also I started the project based in the desktop preview using flexbox and when I saw the mobile I noticed that I would need to change to grid display. A gentle reminder to think a little bit more in which one use before start styling.

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

I'd appreciate any feedback!
