SIgn up preview component using Mobile-first workflow

It was fun getting along with this project but it took me longer than expected to complete, as this was my first project ever on form validation and it's dynamics, but I'm glad it was successful! Special thanks to @elaineleung's solution code which helped me in refactoring my code and learning better ways of making the form validate. I believe subsequent form-like projects won't be an issue (I hope so😆).

I would appreciate feedbacks on possible areas of improving my layout or my code. Thanks!

Time to move into Junior Projects!😁😂
