center image preview with lightbox and caption

I just wanted a thumbnail or preview of the image, where if clicked it would load into a lightbox, but the preview just shows the center of whatever image is added to it. 

Note: I just picked random images and they are centered, so... /runs

HTML

<a href='https://i.imgur.com/2S7oKAT.png' class='fancybox'>
  <div class='image-bg'></div>
  <figcaption>Click This Image! (or dont...)</figcaption>
</a>

<!-- so now we can just switch the image source, but it needs a new bg class for each, which is annoying, unless we move to ... inline styles -->
<!-- It does make it a bit more messy, but easier to update inline. -->
<a href='https://images.pexels.com/photos/9589961/pexels-photo-9589961.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260' class='fancybox'>
  <div class='image-bg' style="background:url(https://images.pexels.com/photos/9589961/pexels-photo-9589961.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260) center no-repeat;"></div>
  <figcaption>Click This Image! (or dont...)</figcaption>
</a>

CSS

.image-bg {
  	height:200px;
  	width:100%;
  	margin-bottom:10px;
  	background:url(https://i.imgur.com/2S7oKAT.png) center no-repeat;
  	background-size:cover;
}
/*  */

              }
          }
