Responsive card-feature with CSS flexbox

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

I am proud of giving it a try

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

the box shadow shade is something I could not figure out as the custom colors didn't match the design. Adding the box-shadow at all except the top was quite difficult but we did it

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

I need input on sizing and maintaining an exact width with a given design
