I know this question might have been answered before but i tried everything i found here.
I want to hide the <app-sidebar>
here's the jsfiddle: https://jsfiddle.net/caght5uf/5/
The iframe I have:
document.getElementById('myiframe').onload = function() {
console.log("iframe content loaded");
var iframee = document.querySelector('.iframe-class');
var link = document.createElement("style");
link.innerHTML = "app-sidebar{display:none;}.mobile-filter-container{display:none;}";
iframee.document.head.appendChild(link);
};<iframe src="https://dorlaaparicio.com/wp-content/plugins/bullhorn-oscp/#/" width="100%" height="600px" scrolling="yes" class="iframe-class" frameborder="0" id="myiframe"></iframe>
