Responsive four card feature section page with CSS Grid

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

Being introduced with CSS grid, make a complicated layout more achievable.

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

The challenge I encountered: How to make the colorful line on the top of each card looks exactly the same as in the design. What I used right now is border-top property, but still has a slightly different.

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

Need to have more experience in:

• Semantics HTML in depth.
• Make an efficient, modular, maintainable CSS code to work with a team.
• BEM naming convention
