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

  • Last Updated : 31 Jan, 2020


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.



  • HTML Code:




    <!DOCTYPE html>
    <html>
    <meta charset="utf-8">
      
    <head>
      
        <link rel="stylesheet" href=
        <script src=
        </script>
        <script src=
        </script>
    </head>
    <body>
        <br>
        <br>
        <center>
            <h1 class="text text-success">GeeksforGeeks</h1>
            <b>Responsive image gallery</b>
        </center>
        <br>
        <br>
        <div class="container-fluid">
            <center>
                <div id=gallery>
                    
                    <!-- Content is appended here -->
                </div>
            </center>
      
            <!-- Modal -->
            <div class="modal fade" id="myModal" role="dialog">
                <div class="modal-dialog">
      
                    <!-- Modal content-->
                    <div class="modal-content">
                        <div class="modal-header">
                            <button type="button" class="close" 
                                    data-dismiss="modal">
                              ×
                            </button>
      
                        </div>
                        <div class="modal-body">
                        </div>
                        <div class="modal-footer">
                               
                        </div>
                    </div>
                </div>
          </div>
      </div>
        
    </body>
      
    </html>

    Desingning structure: We’ll be adding CSS properties as per the requirement in the project.

    • CSS Code:




      <style>
          
          img {
              border-radius: 8px;
          }
            
          .container-fluid {
              margin-left: 12px;
              margin-right: 12px
          }
            
          .contain {
              padding-top: 8px;
              padding-bottom: 8px;
          }
      </style>
    • 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.




      <style>
          /* For overriding box-shadow and other default
             effects of modal and it's children */
          .modal,
          .modal-content,
          .modal-header,
          .modal-footer {
              background-color: transparent;
              border: 0px;
              color: white;
              
              /* Disable box shadow for different browsers */
              -webkit-box-shadow: 0px 0px 0px 0px rgba(255, 255, 255, 1);
              -moz-box-shadow: 0px 0px 0px 0px rgba(255, 255, 255, 1);
              box-shadow: 0px 0px 0px 0px rgba(255, 255, 255, 1);
          }
            
          .modal-dialog {
              width: 100%;
              height: 50%;
              margin-top: 8px;
          }
            
          .close {
              color: white;
              opacity: 0.8;
          }
            
          .modal-body {
              height: 75%;
          }
      </style>

    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.

    Final Solution: This is the combination of the above three-section, this is the complete responsive image gallery code.
