Hello There,
To accomplish what you have in mind, you will need to add this custom JS code:
jQuery(document).ready(function($){
$(window).scroll(function(){
if ($(this).scrollTop() > 100) {
$('body.x-navbar-fixed-top-active .x-navbar-wrap').css("height", "65px");
$('.x-navbar-inner').css("min-height", "65px");
$('.x-brand.img').css("margin-top", "11px");
$('.x-brand img').css("width", "150px");
$('.x-navbar .desktop .x-nav > li > a').css({"padding-top": "30px", "height": "65px"});
} else {
$('body.x-navbar-fixed-top-active .x-navbar-wrap').css("height", "100px");
$('.x-navbar-inner').css("min-height", "100");
$('.x-brand.img').css("margin-top", "20px");
$('.x-brand img').css("width", "250px");
$('.x-navbar .desktop .x-nav > li > a').css({"padding-top": "45px", "height": "100px"});
}
});
});
jQuery ( function($) {
$(window).scroll( function() {
if ( $(this).scrollTop() <= 0 ) {
$('.x-navbar.x-navbar-fixed-top').removeClass( 'x-navbar-fixed-top' );
}
} );
} );
Hope this helps. Please let us know how it goes.
