This is if you are resizing the window, you need to add JS to your theme to handle the resize. This is what I added to my theme:
// Load Events
jQuery(document).ready(() => routes.loadEvents());
document.addEventListener(‘DOMContentLoaded’, function() {
(function() {
$(window).on(‘resize’, function(e) {
var barHeight;
// Show notification bar
if ( jQuery(‘.mtsnb’).length > 0 ) {
barHeight = jQuery(‘.mtsnb’).outerHeight();
jQuery(‘body’).css(‘padding-top’, barHeight).addClass(‘has-mtsnb’);
}
});
})();
});
