Let’s get started!
Step 1: Setting Up the HTML Structure
Any website project starts off with HTML. To create the popup image slider, we will require a basic HTML structure. Below is a simple code block that displays multiple images. The image will open in a modal popup on click.
HTML CODE:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Popup Image Slider</title> </head> <body> <!-- Image thumbnails --> <img class="popup-image" src="image1.jpg" alt="Image 1"> <img class="popup-image" src="image2.jpg" alt="Image 2"> <img class="popup-image" src="image3.jpg" alt="Image 3"> <!-- Modal for full-screen images --> <div id="imageModal" class="modal"> <span class="close">×</span> <!-- Close button --> <img class="modal-content" id="modalImage"> <span class="prev">❮</span> <!-- Left arrow --> <span class="next">❯</span> <!-- Right arrow --> </div> </body> </html>
In the following HTML, we have three images with the class popup-image; they’re clickable and open the popup image slider. The div with class modal encapsulates the popup, on which the large version of the clicked image would be visible. Additionally, we include left (prev) and right (next) arrows for navigation purposes.
Step 2: Styling the Popup in CSS
Now, let us add the style to our popup modal and images. The mode popup will fill the screen, and its images will be centralized and big in the middle of the popup.
CSS Code
<style>
/* Style for modal popup */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.8); /* Black background with opacity */
z-index: 1;
padding-top: 50px;
}
/* Style for modal content (image) */
.modal-content {
display: block;
max-width: 90%;
max-height: 90%;
margin: auto;
}
/* Close button */
.close {
position: absolute;
top: 20px;
right: 35px;
color: white;
font-size: 40px;
cursor: pointer;
}
/* Navigation buttons */
.prev, .next {
position: absolute;
top: 50%;
color: white;
font-size: 40px;
padding: 10px;
cursor: pointer;
user-select: none;
}
.prev {
left: 20px;
}
.next {
right: 20px;
}
/* Style for image thumbnails */
.popup-image {
width: 300px;
cursor: pointer;
margin: 10px;
}
</style>
It is styled here to occupy the full screen height with a semi-transparent black background using the class .modal. The following class is .modal-content that will center the image, set its maximum width and height to 90% of the screen size. The classes .prev and .next are two classes that style the navigation arrows, both on the left and right sides of the screen. Then there’s a class named .close which styles the close button that will dismiss the modal.
Step 3: Bringing interactivity with JavaScript
Core popup image slider code comes with JavaScript. The click functionality is used in opening the modal; it will display the image clicked on and navigational controls so that you can be able to view images by using left and right arrows
JavaScript Code:
<script>
var modal = document.getElementById('imageModal');
var modalImage = document.getElementById('modalImage');
var closeBtn = document.getElementsByClassName('close')[0];
var prevBtn = document.getElementsByClassName('prev')[0];
var nextBtn = document.getElementsByClassName('next')[0];
var images = document.getElementsByClassName('popup-image');
var currentIndex = 0;
// Function to open modal and display clicked image
function showModal(index) {
modal.style.display = "block";
currentIndex = index;
modalImage.src = images[currentIndex].src;
}
// Loop through all images and add click event listener
for (let i = 0; i < images.length; i++) {
images[i].onclick = function() {
showModal(i);
}
}
// Close modal on close button click
closeBtn.onclick = function() {
modal.style.display = "none";
}
// Navigate to the previous image
prevBtn.onclick = function() {
currentIndex = (currentIndex === 0) ? images.length - 1 : currentIndex - 1;
modalImage.src = images[currentIndex].src;
}
// Navigate to the next image
nextBtn.onclick = function() {
currentIndex = (currentIndex === images.length - 1) ? 0 : currentIndex + 1;
modalImage.src = images[currentIndex].src;
}
</script>
This JavaScript code is enabling the modal popup functionality. When clicking on any image, the modal opens up and shows the clicked image inside the modal. Navigation buttons – prev and next – enable cycling of images. The close button hides the modal once clicked.
