Product Preview Card Component Front-End Mentor Challenge

I found this project to be a little complicated but I followed the suggestions and tips from Kevin Powell on Youtube.

I learned a lot from this project and I hope you can as well, if you are a newbie like I currently am.

At first I had issues with the root code but I figured out that when they say the computer is never wrong, they're right.

My only question is, what ways would you suggest are better practices?

Thank you.
