Responsive pod access landing page using a Mobile-First Approach

Hello, everyone!!! Glad to announce that I have just concluded this challenge using HTML, CSS, and JavaScript. I found this one a bit challenging but I feel I did a decent with what I was able to code up. I learned a bunch of new concepts, especially when doing the form validation using the constraint validation API and how to perform other client-side validation using JavaScript.

I am open to any corrections and improvements provided by the community.
