The template comes with sticky header functionality, that makes pages navigation together with the menu much more convenient. Sticky header is available in 4 animation variations - Slide, Swing, Flip, Bounce. You can choose one you like most. For this find the following code in js/main.js file:
CRUMINA.fixedHeader = function () {
// grab an element $header.headroom( { "offset": 10, "tolerance": 5, "classes": { "initial": "animated", "pinned": "slideDown", "unpinned": "slideUp" } } );};

In order to deactivate sticky header function, you just need to delete the line id="site-header" from HTML markup, namely from:
<header class="header" id="site-header">...</header>
To bring it to this look:
<header class="header">...</header>.
