Hi @afolabi4u2,
You can try the following custom CSS to customize the button on the form.
.everest-forms .everest-forms-part-button, .everest-forms button, .everest-forms button[type=submit], .everest-forms input[type=submit] {
background: #009688;
border-color: #009688;
color: #fff;
}
You can change the styles on the hover by using the following custom CSS.
.everest-forms .everest-forms-part-button:hover, .everest-forms button:hover, .everest-forms button[type=submit]:hover, .everest-forms input[type=submit]:hover {
background: #006f65;
border-color: #006f65;
color: #fff;
}
You can change the color code as your preference.
Regards.
