Adding Lightboxes to Images

Lightboxes allow your customers to expand an image or a GIF for a closer look. This might be useful for the little details they can't quite see without expanding or accessibility for people with vision impairment.

The CSS

/* For image lightbox */
.mfp-bg { z-index: 9999 !important; }
.mfp-wrap { z-index: 10000 !important; }
.lightbox:focus { outline: none !important; }

The JavaScript

<link href="https://cdnjs.cloudflare.com/ajax/libs/magnific-popup.js/1.1.0/magnific-popup.min.css" type="text/css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/magnific-popup.js/1.1.0/jquery.magnific-popup.min.js" type="text/javascript"></script>
<script type="text/javascript">
    (function() {
        $(function() {
          $('#article img').each(function() {
            $(this).wrap('<a></a>');
            $(this).parent().addClass('lightbox').attr('href', $(this).attr('src'));
          });
          $('.lightbox').magnificPopup({
              type: 'image',
              closeOnContentClick: true,
              mainClass: 'mfp-img-mobile',
              image: {
                  verticalFit: true
              }
          });
        });
    })();
</script>
