Does the submit button have to be in the form?

You can tie a submit button to a form that the button doesn't live inside of. The trick is to give the form an id and then reference that id with the button's form property. With this setup, clicking the Submit button will cause the form to be submitted. See the MDN Button docs for more details.

What happens when submit button is clicked?

5.

Most HTML forms have a submit button at the bottom of the form. Once all of the fields in the form have been filled in, the user clicks on the submit button to record the form data. The standard behaviour is to gather all of the data that were entered into the form and send it to another program to be processed.

Where should the submit button be?

Submit buttons are placed at the bottom of the page to optimize top to bottom flow. There should always be two buttons, a primary action button that will commit changes made by the user and a Cancel button that will abort those changes.
