Hi!
Thought I would post this if others that come across this thread have no idea how to embed a Youtube video on their profile, but would like to. I use div on my Social Center profile page. One of many ways to do it.
Copy and paste embed code from Youtube and replace what I have below from iframe to iframe. If you would like it to auto play put &autoplay=1 at the end of https path just before closing quotation. In my example it would look like Youtube&autoplay=1".
Code: <li>
<div align="center"><iframe width="560" height="315"
src="https://www.youtube.com/embed/whatever this part is from Youtube"
frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope;
picture-in-picture" allowfullscreen></iframe></a></div>
</li>
I almost forgot. You can't test many YouTube videos on your computer especially popular music videos. You will get video unavailable trying to play it using Dreamweaver etc. Seems Youtube prevents that, it has to be on a website.
