Features:

• Open/close animations: zoomIn, fade and zoom.
• Content slide animations: fade, slide, zoom.
• Support any content and even mixed content: images, HTML5 videos, Youtube/Vimeo videos, iframes, inline contents and much more.
• Fully accessible with keyboard interactions.
• Lots of configuration options, callback functions, and API methods.

How to use it:

Import the ‘glightbox.css’ and ‘glightbox.js’ into the document.

<link href="dist/css/glightbox.css" rel="stylesheet">
<script src="dist/js/glightbox.js"></script>

Specify the content to be loaded in the gallery lightbox using ‘href’ attribute. Note that the grouped media content must have the same class.

<a href="https://vimeo.com/115041822" class="glightbox-demo">
  <img src="https://picsum.photos/400/300/?random" alt="image">
</a>

Create a Facebook like gallery lightbox and config the item using the following attributes:

• title
• description
• descPosition: bottom, top, left, right
• type: media type
• effect: slide, fade, zoom, none
• width
• height

<a href="1.jpg" class="glightbox-demo" data-glightbox="title:Description Bottom; description: You can set the position of the desciption">
  <img src="thumb.jpg" alt="image">
  <div class="glightbox-desc">
    <p>Description here</p>
  </div>
</a>

Initialize the Glightbox library and done.

var myLightbox = GLightbox({
    'selector': 'glightbox-demo'
});

You can also define the content in the JavaScript using the elements option.

var myLightbox = GLightbox({ 
    elements: [
      {
        'href': '1.jpg',
        'type': 'image',
        'title': 'My Title',
        'description': 'Example',
      },
      {
        'href': 'https://www.youtube.com/watch?v=Ga6RYejo6Hk',
        'type': 'video',
        'source': 'youtube',
        'width': 900
      }
  ],
});

Here is a list of all possible options and callback functions to customize the gallery lightbox.

var myLightbox = GLightbox({ 

    // default selector
    selector: 'glightbox',
