# Lightbox

Lightbox flipbook displays flipbook thumbnail on the page and opens the flipbook in a fullscreen overlay when the thumbnail is clicked. There are other options to open the lightbox flipbook, like using a CSS class or using hash navigation (deep linking). Thumbnail can be hidden if the flipbook should be opened from a button or text link.

## **CSS class**

Any element on the page containing flipbook shortcode that has this CSS class will trigger the lightbox.
