Four Card Feature Section build with React

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

Using pseudo-classes to add the correct border color for every card and implementing a grid area and set the grid items to their correct position.

PS: no idea why the screenshot is missing 2 cards. Maybe because of the animation styles? All works fine on the live site.

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

How to use the pseudo-classes and add some simple fade in animation for the cards. Found the solutions on MDN.

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

Animations! The short-hand property is pretty overwhelming and I wonder if the code is written correctly.
