:-moz-submit-invalid

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The :-moz-submit-invalid CSS pseudo-class represents any submit button on forms whose contents aren't valid based on their validation constraints.

By default, no style is applied. You can use this style to customize the appearance of the submit button when there are invalid form fields.
