So, I'm confused pretty severely... So I went to w3Schools iFrame page. Copy and pasted this code into codepen directly from w3schools...
<iframe src="https://www.w3schools.com"></iframe>
I also tried changing the URL a few times. Loading Google even didn't work... All that happens is a blank page with the same background color as the parent page. I dont understand why the iframe code even from w3schools doesn't work... Am i not loading a dependency? I'm using the latest version of chrome.

Check this one Checking if a website doesn't permit iframe embed and this one too Certain websites won't appear with Iframe and .load() function. I had same problem few year back then i came through these,some sites avoid iframe tag.
