All solutions

I'd like to get some feedback about the methods and techniques I used. Can they be improved or are they just okay? I would also appreciate any other thing that you think is worth mentioning.

Please have a look at the code and tell me where I can improve. All feedback will be appreciated.

It took me some time to find a way to vertically align the cards. And I also struggled with using media queries, (1440px didn't seem to do it). It worked fine locally but it didn't when I put it on github and vercel. Please help me anyhow you can.
