Video player

GLightbox includes "Plyr" the best player out there, you can pass any Plyr option to the player, view all available options here Plyr options. GLightbox will only inject the player library if required and only when the lightbox is opened.

Internet Explorer 11. If you need support for this browser you need to set the js url to use the polyfilled version. This is not the default because IE11 is ancient and we need to let it die.

Autoplay for mobile/tablet

Please note, autoplay is blocked in some browsers, there’s nothing we can do to change that unfortunately, the browser will decide if your video can be autoplayed. Please do not post issues about this, instead inform yourself about this topic:

they decide if a video can be autoplayed based in a few rules

plyr: {
    js: 'https://cdn.plyr.io/3.6.2/plyr.polyfilled.js',
    ....

const lightbox = GLightbox({
  plyr: {
    css: 'https://cdn.plyr.io/3.5.6/plyr.css', // Default not required to include
    js: 'https://cdn.plyr.io/3.5.6/plyr.js', // Default not required to include
    config: {
      ratio: '16:9', // or '4:3'
      muted: false,
      hideControls: true,
      youtube: {
        noCookie: true,
        rel: 0,
        showinfo: 0,
        iv_load_policy: 3
      },
      vimeo: {
        byline: false,
        portrait: false,
        title: false,
        speed: true,
        transparent: false
      }
    }
  }
});

API

There are methods, setters and getters on a GLightbox object. The easiest way to access the GLightbox object is to set the return value from your call to a variable. For example:

const lightbox = GLightbox({ ...options });

Methods

Example method use:

lightbox.nextSlide(); // Go to next slide
lightbox.close(); // Close the lightbox

on	`string, function`	Set an event listener. See Events section
once	`string, function`	Set an event listener that will be triggered only once. See Events section

// Example set custom gallery items
// This overwrites all the items in the gallery
lightbox.setElements([
  {
    'href': 'https://picsum.photos/1200/800',
    'type': 'image' // Type is only required if GLightbox fails to know what kind of content should display
  },
  {
    'href': 'https://www.youtube.com/watch?v=Ga6RYejo6Hk',
    'type': 'video', // Type is only required if GLightbox fails to know what kind of content should display
    'width': '900px',
  },
  {
    'content': '<p>some html to append in the slide</p>',
    'width': '900px',
  }
]);


// Insert a single slide at the end of all the items,
lightbox.insertSlide({
    href: 'video url...',
    width: '90vw'
});

// Insert a single slide at index 2 or pass 0 to add it at the start
lightbox.insertSlide({
    href: 'video url...',
    width: '90vw'
}, 2);

// You can insert a slide with a defined html
lightbox.insertSlide({
    content: '<p>some html to append in the slide</p>',
    width: '90vw'
}, 2);

// Or if you prefer you can pass a node
// and it will be inserted in the slide
lightbox.insertSlide({
    content: document.getElementById('inline-example'),
    width: '90vw'
}, 2);

// Remove the slide at index 2
lightbox.removeSlide(2);

// Open the lightbox
lightbox.open();

// You can also open the lightbox at a specific index
lightbox.openAt(2);

// So imagine that you are making an ajax request that returns some html
// You can create an empty instance and append the content once is returned

const ajaxExample = GLightbox({ selector: null }); // or you can set the selector empty selector: ''

doAjaxCall({...}).then(response => {
    ajaxExample.insertSlide({
        width: '500px',
        content: response.html
    });
    ajaxExample.open();
})

// Or you could use the set elements method to empty all the slides if any

doAjaxCall({...}).then(response => {
    ajaxExample.setElements([
      {
        content: response.html
      }
    ]);
    ajaxExample.open();
})

Animations

Animations are created with CSS, each effect has an in and out value and they are used to attach the correct classes to the node.

For example if you are using

const glightbox = GLightbox({
  openEffect: 'zoom',
  closeEffect: 'fade',
  cssEfects: {
    // This are some of the animations included, no need to overwrite
    fade: { in: 'fadeIn', out: 'fadeOut' },
    zoom: { in: 'zoomIn', out: 'zoomOut' }
  }
});

The open effect will use cssEfects.zoom.in and will add the class gzoomIn, if you take a look at the CSS you'll see:

.gzoomIn {
    animation: gzoomIn .5s ease;
}

@keyframes gzoomIn {
    from {
        opacity: 0;
        transform: scale3d(.3, .3, .3);
    }
    to {
        opacity: 1;
    }
}

Adding a custom animation

You can create any animation you want, you can find some inspiration in the Animate.css library, for example you can add the bounce animation like this:

const glightbox = GLightbox({
  openEffect: 'bounce', // Define that we want the bounce animation on open
  cssEfects: {
    // register our new animation
    bounce: { in: 'bounceIn', out: 'bounceOut' }
  }
});

/*A g will be appended to the animation name so bounceIn will become gbounceIn */
.gbounceIn {
  animation: bounceIn 1.3s ease;
}

@keyframes bounceIn {
  from,
  20%,
  40%,
  60%,
  80%,
  to {
    animation-timing-function: cubic-bezier(0.215, 0.61, 0.355, 1);
  }

  0% {
    opacity: 0;
    transform: scale3d(0.3, 0.3, 0.3);
  }

  20% {
    transform: scale3d(1.1, 1.1, 1.1);
  }

  40% {
    transform: scale3d(0.9, 0.9, 0.9);
  }

  60% {
    opacity: 1;
    transform: scale3d(1.03, 1.03, 1.03);
  }

  80% {
    transform: scale3d(0.97, 0.97, 0.97);
  }

  to {
    opacity: 1;
    transform: scale3d(1, 1, 1);
  }
}

Themeable

You can completely customize the structure of GLightbox and use CSS to change any part you want.

const customLightboxHTML = `<div id="glightbox-body" class="glightbox-container">
    <div class="gloader visible"></div>
    <div class="goverlay"></div>
    <div class="gcontainer">
    <div id="glightbox-slider" class="gslider"></div>
    <button class="gnext gbtn" tabindex="0" aria-label="Next" data-customattribute="example">{nextSVG}</button>
    <button class="gprev gbtn" tabindex="1" aria-label="Previous">{prevSVG}</button>
    <button class="gclose gbtn" tabindex="2" aria-label="Close">{closeSVG}</button>
</div>
</div>`;

let customSlideHTML = `<div class="gslide">
    <div class="gslide-inner-content">
        <div class="ginner-container">
            <div class="gslide-media">
            </div>
            <div class="gslide-description">
                <div class="gdesc-inner">
                    <h4 class="gslide-title"></h4>
                    <div class="gslide-desc"></div>
                </div>
            </div>
        </div>
    </div>
</div>`;

const glightbox = GLightbox({
  lightboxHTML: customLightboxHTML,
  slideHTML: customSlideHTML,
  skin: 'supercool'
});

You can also define a skin name and the lightbox will append the class name "glightbox-supercool" so you can customize it with CSS, this will leave a barebones structure so you can change the buttons appearance, etc.
