How to create responsive image gallery using HTML, CSS, jQuery and Bootstrap?


With the advent of new frameworks in web technologies, it has become quite easy to design and implement feature-rich and responsive web pages. Here, we are going to design a responsive image gallery using HTML, CSS, jQuery and Bootstrap.

Features or Functionalities to implement:

  • Responsive images
  • Responsive Grid System
  • Image viewer

Prerequisites: Basic knowledge of HTML, CSS, JavaScript, jQuery, and Bootstrap. Also, the user should be aware of how the grid system in Bootstrap works.

We will divide the complete solution into three different sections in the first section we will create the structure for the gallery. In the second section, we will design the gallery by using CSS. And in the last section will make it available to respond to the user’s interactions.

Creating structure: Initialize HTML layout and responsive images, but we will attach the images by jQuery, in an array format.

    • Bootstrap code: We will use a bootstrap modal as image viewer and modify it according to our requirements accordingly. We will render all unnecessary components of modal transparent. Remember, we are appending the image in the modal, so we need to use on() method to attach functionalities for such selectors.

    Respond section: In this section we will attach all the images for the responsive gallery, make them responsive to the user. Below is the grid arrangement we’ll be using for displaying images in the image gallery. Since classes used col-sm-6 col-md-2. The logic is 2-grids for medium screen break-point and 6-grids for large breakpoints. They also divide further whenever content overlaps thereby presenting as a single grid.

    • jQuery code: Below is the script for appending in this manner. We’ll be supposing that we are getting the images from the server (as an array of image URLs in JavaScript). Now we will append the image accordingly in the content panel of our page. Below is the implementation for the same
