Is this Registration form good enough to make A simple vanilla Javascript validation form

So far I only added the HTML and CSS part of the form. I don’t want to use this form if the current CSS/HTML aspect of this form is not compatible with the vanilla JS aspect of this form. I like to hear your thoughts.

  • Run your HTML code through the W3C validator.
  • Don’t use <br> to force line breaks
