HTML and CSS | Four Card Feature Section

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

This is probably my first, at least, mobile-responsive using media query. I tried using Tailwind css on this challenge but I keep having issues on the border top color so I revert back to pure CSS.

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

Tailwind issues and media queries. I resolved it through research and asking in the forums. I just keep getting challenges and push through to learn.

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

More on refining my process, from the design to the HTML structure and styling. I think it would be best if there is someone who can guide me with this. Also, what are the industry standards that they are using to help become a better frontend developer.
