How to customize "Back" and "Next" button in a multipage form?

We have custom png files for the next and back buttons that we would like to use.
How can this be done?

Hi, in order to add an image on the back and next buttons, you need  inject CSS code in your form, you may try the following one:

.form-pagebreak-next{

display:block;

text-size:12px;

float:right;

margin-left: 250px;

background:url("HERE YOU ADD THE URL OF THE IMAGE") no-repeat  !important;

width:155px !important;

height:61px !important;

box-shadow: none !important;

border: none !important;

}

.form-pagebreak-back{

display:block;

text-size:12px;

float:left;

margin-left:20px;

background:url("HERE YOU ADD THE URL OF THE IMAGE") no-repeat  !important;

width:155px !important;

height:61px !important;

box-shadow: none !important;

border: none !important;

}

If you need more help, you may share with us the URL of the form to further assist you.

Thanks !!!
