To make LightBox work, we have to initialize it first.
Below the scripts, place this JavaScript function to initialize the LightBox.
// MDB Lightbox Init
$(function () {
$("#mdb-lightbox-ui").load("mdb-addons/mdb-lightbox-ui.html");
});
Save the file and click on any picture of the LightBox - it works!
Let's have a closer look at the LightBox.
<figure class="col-md-4">
<a href="https://mdbootstrap.com/img/Photos/Lightbox/Original/img%20(145).jpg"
data-size="1600x1067">
<img src="https://mdbootstrap.com/img/Photos/Lightbox/Thumbnail/img%20(145).jpg"
class="img-fluid">
</a>
</figure>
As you can see for each picture we use an image in two different sizes:
-
Big, high-quality image
-
Small image as a thumbnail
We do it for the sake of performance. When the website is loaded we display to the user only thumbnails because if we wanted to render all the big, high-quality pictures it could place undue load on the browser.
But when the user clicks on a particular image - we will render this in its best quality.
Step 2 - shadows
To make the LighBox look even better, we can add a shadow to the images.
Add a .z-depth-1-half class to each thumbnail.
<figure class="col-md-4">
<a href="https://mdbootstrap.com/img/Photos/Lightbox/Original/img%20(145).jpg"
data-size="1600x1067">
<img src="https://mdbootstrap.com/img/Photos/Lightbox/Thumbnail/img%20(145).jpg"
class="img-fluid z-depth-1-half">
</a>
</figure>
