Results Summary Component using flexbox

I would like some input regarding my way of coding and I would love some feedback as to what I can improve or any suggestions that I should've done to make coding easier.

The hardest part of this challenge is getting the width. I used 2 div for 'Your Result" and "Summary" Panel and I set their width to 375px to make it wrap when opened in a smaller screen. It's the only band-aid solution that I can come up with.

All input and corrections are welcome. I would like to do this challenge again with a best coding practice and better results.
