Four card feature section solution

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

My solution appears very similar to both mobile and desktop design.

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

I was unfamiliar with box shadow and this challenge was able to push me towards learning the basics.

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

Specifically would like any suggestions if needed in regards to how I wrote out the svgs in my HTML. I'm aware there is an svg element but was unsure if it was necessary for this project. Would like more clarity on that. Would also like any suggestions to make my box-shadow a little closer to design.

Any refactoring or structuring suggestions to both my HTML and my CSS is gladly welcomed!
