Demos are largely unstyled to give developers a better idea of how the plugin can drop into a new or existing project.

Using Lightbox




viewer.js (optional)


Display images and videos in an overlay:

<a href="one.jpg" title="Image Caption">
  <img src="one_thumb.jpg" alt="">


Link multiple images or videos together with the data-lightbox-gallery attribute:

<a href="one.jpg" title="Image Caption One" data-lightbox-gallery="photo_gallery">
  <img src="one_thumb.jpg" alt="">
<a href="two.jpg" title="Image Caption Two" data-lightbox-gallery="photo_gallery">
  <img src="two_thumb.jpg" alt="">
<a href="three.jpg" title="Image Caption Three" data-lightbox-gallery="photo_gallery">
  <img src="three_thumb.jpg" alt="">


React to the lightbox by listening for the open.lightbox and close.lightbox events on the window:

$(window).on("open.lightbox", function() {
  // ...
}).on("close.lightbox", function() {
  // ...


Set instance options by passing a valid object at initialization, or to the public defaults method. Custom options for a specific instance can also be set by attaching a data-lightbox-options attribute to the target elment. This attribute should contain the properly formatted JSON object representing the custom options.
