Mobile-first Interactive card details form

Helloo good day! This challenge took me some time to finish because I wanted to make it have a credit card validation and it's unfortunate that I wasn't able to find out sooner that a credit card validator library exists from npm and I had to do it the hard way that's why it took me so long. I had to look up for solutions online particularly on stackoverflow. I would like to give huge thanks to the people from stackoverflow for the resources I got. I was able to learn and have some idea about libraries and packages along the way. Please feel free to give some feedback and I would appreciate it. Thankyouuu. 💕
