All You Need to Know About Bootstrap Gallery

When you need to keep your user engaged to increase the stay time or session of your website, you need to add videos, images or other sources of media to keep them busy. The Bootstrap gallery is easy to construct.

In this blog, we shall see how to design:

• A bootstrap gallery with image filtering
• A Lightbox bootstrap gallery
• Carousel Bootstrap Gallery

As complicated as it sounds, all of the above examples can be created easily. Let’s get started!

A bootstrap gallery with image filtering

If you would like to add an option of segregating your images into different categories, you’ll have to use an image filtering option.

There are three parts involved while creating a gallery:

• HTML
• CSS
• JavaScript

First, create a grid row and column as necessary, then add the images. Read the comments before every line of code, to understand the code better.

HTML Code

<!-- Grid row →
<div class="row">
<!-- Grid column -->

<div class="col-md-12 d-flex justify-content-center mb-5">
<button type="button" class="btn btn-outline-black waves-effect filter" data-rel="all"> All </button>
<button type="button" class="btn btn-outline-black waves-effect filter" data-rel="1">Mountains</button>
<button type="button" class="btn btn-outline-black waves-effect filter" data-rel="2">Sea</button>
</div>

<!-- Grid column →
</div>

<!-- Grid row -->
<!-- Grid row →

<div class="gallery" id="gallery">
<!-- Grid column -->
<div class="mb-3 pics animation all 2">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Horizontal/Nature/4-col/img%20(73).jpg" alt="Card image cap">
</div>

<!-- Grid column -->
<!-- Grid column →

<div class="mb-3 pics animation all 1">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Vertical/mountain1.jpg" alt="Card image cap">
</div>
<!-- Grid column -->

<!-- Grid column -->
<div class="mb-3 pics animation all 1">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Vertical/mountain2.jpg" alt="Card image cap">
</div>

<!-- Grid column -->
<!-- Grid column →

<div class="mb-3 pics animation all 2">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Horizontal/Nature/4-col/img%20(35).jpg" alt="Card image cap">
</div>

<!-- Grid column -->
<!-- Grid column -->
<div class="mb-3 pics animation all 2">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Horizontal/Nature/4-col/img%20(18).jpg" alt="Card image cap">
</div>

<!-- Grid column -->
<!-- Grid column -->
<div class="mb-3 pics animation all 1">
<img class="img-fluid" src="https://mdbootstrap.com/img/Photos/Vertical/mountain3.jpg" alt="Card image cap">
</div>

<!-- Grid column -->

</div>

<!-- Grid row -->

CSS Code

.gallery
{
-webkit-column-count: 3;
-moz-column-count: 3;
column-count: 3;
-webkit-column-width: 33%;
-moz-column-width: 33%;
column-width: 33%;
}
.gallery .pics
{
-webkit-transition: all 350ms ease;
transition: all 350ms ease;
}
.gallery .animation
{
-webkit-transform: scale(1);
-ms-transform: scale(1);
transform: scale(1);
}
@media (max-width: 450px)
{
.gallery
{
-webkit-column-count: 1;
-moz-column-count: 1;
column-count: 1;
-webkit-column-width: 100%;
-moz-column-width: 100%;
column-width: 100%;
}
}

@media (max-width: 400px)
{
.btn.filter
{
padding-left: 1.1rem;
padding-right: 1.1rem;
}
}

JavaScript Code

$(function()
{
var selectedClass = "";
$(".filter").click(function()
{
selectedClass = $(this).attr("data-rel");
$("#gallery").fadeTo(100, 0.1);
$("#gallery div").not("."+selectedClass).fadeOut().removeClass('animation');
setTimeout(function()
{
$("."+selectedClass).fadeIn().addClass('animation');
$("#gallery").fadeTo(300, 1);
}, 300);
});
});

Output:

There’s an option to view “All” images, “Mountains”, or just “Sea” images.

When you click on the mountains option, this is what appears:

When you choose the sea option, this is what appears:

Next, let’s learn how to create a Lightbox image bootstrap gallery.

Lightbox Gallery

Lightbox is mostly used to portray a complied presentation of someone’s work. Here the “.mdb-lightbox” class is used to There are two parts involved in creating a Lightbox bootstrap gallery:

• HTML
• CSS

HTML Code

Carousel bootstrap gallery

When you’re short on space on your webpage, a carousel gallery comes in handy. Multiple images can be added by occupying a small space on the site. End users can scroll through these images with the help of buttons.

Carousel gallery consists of two parts:

• HTML
• CSS

HTML Code

In the Carousel bootstrap gallery, you first create the controller(the buttons) and then create the slides as per requirement.

<!--Carousel Wrapper-->
