The content mode is enabled by setting the type property to content, which provides an anchor (or link) to open the LightBox and content to display inside of it. A customized content example of a LightBox with a collection of Angular conferences would be as follows:

<p-lightbox type="content" name="content">
  <a class="group" href="#">
    Watch PrimeNG Video
  </a>
  <iframe width="500" height="300" 
    src="https://www.youtube.com/watch?v=Jf9nQ36e0Fw&t=754s"
    frameborder="0" allowfullscreen></iframe>
</p-lightbox>

The component will be rendered as iframe video inside Overlay panel as shown in the following screenshot:

As shown the preceding snapshot, the list of videos are displayed and can watch videos in a popup mode for better experience.
