Interactive Credit Card Form with REGEX validation.

I used the design provided by Front-end mentor to make a form with a functional validation, in order to test the use of Regex, DOM manipulation and to put in practice the building of an algorithm from scratch using vanilla JS.

The form only allows you to submit if all the input fields are filled in correctly, just like in a real form

It was a project that I really enjoyed doing to test my skills, and even though I translated it to my language I believe it's very intuitive for any user to understand.

Feedback are always welcome :)
