How do I remove the rollover border and change the text colour to white on this submit button?

For the mouseover, I'd like to remove the border and change the text to white. See attached.

To remove the border and change the text to white in the mouseover, please add this custom CSS code to your form: 

.form-submit-button:hover { 

    border: 0px !important; 

    color: white !important; 

} 

Please follow this guide on how to add custom CSS code to your form: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

Here's the result:

It only works in the working form. Does not work in preview or live mode. The black border and black text is still there.

To remove the black border and text add this CSS code to your form:

button#input_2 {

    border: none!important;

    color: white!important;

}
