Create a persistent pop up floating window using JavaScript/HTML/CSS
<p>I've been looking around, but I can't think of the correct terminology to describe what I want (and hence get the results that I want from searching).</p>

<p>I'm going to be integrating the QuickBlox video chat into an existing web app. I've been asked to display the video window in a type of persistent floating window that will allow the user to continue using the website while they still have the video chat window open and chatting with the person (eg they could be chatting with a trainer, who might ask them to visit a specific page).</p>

<p>Is this type of thing possible with html/js/css? I need this special pop up window to be persistent and stay connected to the video chat.
