back and submit button

how can i get the back button on same line of the submit but opposite side?

First you would need to make your back button to be visible. Then you can enter this CSS code to position your back and submit button:

.form-pagebreak

{

margin: 0px 0px;

border-style: none;

padding-left: 36px ;

height: auto;

overflow: hidden;

}

.form-pagebreak-next-container, .form-pagebreak-back-container {

margin-top: 3px;

margin-bottom: 3px;

padding: 0px 3px 0px 0px;

}

.form-pagebreak-back,

.form-pagebreak-next

{

width:125px !important;

height:33px !important;

font-size: 14px !important;

color: #000 !important;

font-weight : bold !important;

}

.form-submit-button {

position: absolute !important;

margin-top:3px !important;

top: 20px !important;

right: 50px !important;

font-size: 14px !important;

color: #000 !important;

font-weight : bold !important;

width:125px !important;

height:33px !important;

}

After you add this code your back and submit button should be aligned like this.
