Lightbox Display
Use this element to display linked content in a Lightbox view. This element is useful for displaying full-size versions of images linked from a table of thumbnail images, or opening a video player from a widget or thumbnail image.
How to use this element
The Lightbox Display will be applied to any links within a page that are contained within a block with the 'lightbox' style assigned. As an example, if you have a group of thumbnail images in a rich-text editor element, you can add the 'lightbox' class to the element's style settings.

Once the style is set, add the Lightbox Display element from the Content Well element gallery category, and configure as needed.
Display Options
You can modify the overlay color, opacity of that color, the border around the content, the content type, and width and height of the content display. For links to images, the 'type' can be set to 'any'. The element will attempt to figure out what content type to set based on the link URL. If you're linking to content embedded in an html page, such as a video player, you would select the 'iframe' type.
In this example, the widget images are linked to html pages with a Flash player and video content, so we've set the type to 'iframe', and we've changed the width and height settings to match the dimensions of the video player.
