How do I keep the text on the submit button centered?

Also, the text on the submit button is sometimes flush to the bottom of the button instead of remaining centered. Any help you can provide would be appreciated. 

Just simply inject the following custom CSS codes to your form:

.form-all .form-submit-button {

  line-height: 2px;

}

The same guide on how to inject a custom CSS codes to your form (http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes).

Thanks
