Now we are able to make our Unbounce Header like in our Magento store. You need to put the code below to your JavaScript file.
<script type="text/javascript">
// Fixed Header v1.1
// Replace ID below with your own box ID
var boxToAppend = '#lp-pom-box-291';
var boxParent = $(boxToAppend).parent();
$(boxToAppend).clone().appendTo(boxParent).css({
"position": "fixed",
"left": "0",
"top": "0",
"width": "100%",
"z-index": "899"
}).children().remove();
$(boxToAppend).css({
"position": "fixed",
"left": "auto",
"top": "0px",
"width": "100%",
"z-index": "999",
"border-style": "none none none none",
"border-width": "0px",
"background": "none"
});
</script>
