Just want feedback on my code and see what improvements I can make. Thank you!
Hi @Jimmy_Jimenez and welcome to the community 
Amazing work on this exercise! 
Great use of Flexbox, pseudo-classes and pseudo-elements. Maybe one thing I would change is the choice of characters for valid/invalid. Instead of “O” and “X” you could use ✓ (Check Mark) and ✗ (Ballot X).
That’s more a matter of taste, though. 
Happy New Year,
Michael
