I have the hover effect working fine for the normal submit button but it doesn't work for the next and back buttons for some reason. Here is what I was trying.
[css]
body .gform_wrapper .gform_body .gform_page_footer .gform_next_button input[type=image] {
padding: 0;
width: auto !important;
background: url(http://www.ezcanadamoving.com/wp-content/uploads/2012/10/NextButton.png) center top no-repeat !important;
height: 43px !important;
width: 120px !important;
border: none !important
}
body .gform_wrapper .gform_body .gform_page_footer .gform_next_button:hover input[type=image] {
padding: 0;
width: auto !important;
background: url(http://www.ezcanadamoving.com/wp-content/uploads/2012/10/NextButtonHover.png) center top no-repeat !important;
height: 43px !important;
width: 120px !important;
border: none !important
}
