document.addEventListener(‘DOMContentLoaded’, function() { var widgets = document.querySelectorAll(‘.ad-widget-unit’); var fallbacks = document.querySelectorAll(‘.ad-fallback-unit’); setTimeout(function() { widgets.forEach((widget, index) => { var fallback = fallbacks[index]; var isFiltered = ( widget.offsetHeight === 0 || widget.offsetParent === null || window.getComputedStyle(widget).getPropertyValue(‘display’) === ‘none’ ); if (isFiltered) { fallback.style.display = ‘block’; } }); }, 150); });

document.getElementById(‘kznott2frame’).onload = function() {
try {
const contentHeight = this.contentWindow.document.body.scrollHeight;
this.height = contentHeight;
} catch (e) {
console.error(“error”);
}
};
