Responsive Four card feature section using Flexbox

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

I had a hard time on making the section responsive using display Grid and without using media queries. I switched to Flexbox but ended up using media queries anyway, continued using because of flex wrap properties.

I try to practice using media queries as least as possible.

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

Any kind of criticism is welcome!
