Updated version with code here

do people still use lightboxes, it seems yes in some cases. ;)

if you feel the urge to use lightboxes and need to link to some youtube videos this is how you can do it.

you will need jquery and fancybox and a youtube video link for this to work

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/fancybox/3.1.20/jquery.fancybox.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/fancybox/3.1.20/jquery.fancybox.js"></script>

I found this example somewhere, cant remember where that adds the fancybox code to any link with the class video

<script>jQuery(document).ready(function() {

	$(".youtube").fancybox({
	    type: "iframe"
	});

});</script>

Add a link to the video, e.g:

here is a test link

Click it to see if it works...
