This add-on aims to resolve the form validation on your WEB development. Yes, it can be straightforward build a simple solution by listening the `input` event and disable the `continue` button until it's correct. But that's clearly not always the case, especially when the project involve tons of user input. Normally a form validation library can ease the pain and setup a certain standard for consistency. Well, this is one of them, however, we are trying build a tool that is more versatile and not stop you the way.
