How to Create an Image Gallery with a Horizontal Scrollbar Using CSS


In this article, we will explore how to create an image gallery with a horizontal scrollbar using CSS. Image galleries are a popular way to showcase multiple images on a website, and adding a horizontal scrollbar allows for a seamless browsing experience. We’ll provide step-by-step instructions, along with code snippets and examples, to guide you through the process.

1. What is an Image Gallery?

An image gallery is a collection of images displayed together on a web page. It allows users to view multiple images without leaving the page, making it an effective way to present visual content. Image galleries are commonly used in photography portfolios, e-commerce websites, and creative showcases.

2. The Importance of a Horizontal Scrollbar

When the number of images in an image gallery exceeds the available screen width, a horizontal scrollbar becomes crucial for navigating through the images effectively. Without a scrollbar, users may struggle to view all the images, leading to a poor user experience. Implementing a horizontal scrollbar ensures that users can effortlessly explore all the images in the gallery.

3. Understanding CSS Flexbox

CSS Flexbox is a powerful layout model that enables easy positioning and alignment of elements within a container. We will utilize Flexbox to create the horizontal scrolling effect for our image gallery. The Flexbox properties we will use include display: flex, flex-direction, flex-wrap, and justify-content.

4. Setting Up the HTML Structure

To begin, let’s create the basic HTML structure for our image gallery. We’ll use a div element with a class of “gallery-container” to hold the images.

<div class="gallery-container">
  <img src="image1.jpg" alt="Image 1">
  <img src="image2.jpg" alt="Image 2">
  <!-- Add more images here -->

5. Styling the Image Gallery Container

Next, we’ll apply some CSS styles to the “gallery-container” to set its width, height, and other properties.

.gallery-container {
  display: flex;
  flex-wrap: nowrap;
  overflow-x: auto;
  width: 100%;
  height: 400px; /* Set the desired height of the gallery */

6. Creating the Horizontal Scrollable Effect

To achieve the horizontal scroll effect, we’ll use the overflow-x: auto property on the gallery container. This will add a scrollbar horizontally when the images exceed the container’s width.

7. Implementing Navigation Buttons

To enhance user experience, we can add navigation buttons on either side of the gallery to allow users to scroll through the images. Let’s create left and right buttons.

<div class="gallery-container">
  <button class="nav-btn prev-btn">&lt;</button>
  <img src="image1.jpg" alt="Image 1">
  <img src="image2.jpg" alt="Image 2">
  <!-- Add more images here -->
  <button class="nav-btn next-btn">&gt;</button>

8. Adding CSS Transitions for Smooth Animation

To make the scrolling experience smooth and visually appealing, we can add CSS transitions to the gallery container. This will create a gentle sliding animation when the user scrolls.

.gallery-container {
  /* Previous styles */
  transition: transform 0.3s ease-in-out; /* Add this line for smooth scrolling animation */

9. Making the Gallery Responsive

It’s essential to ensure that the image gallery adapts to different screen sizes and devices. We can achieve this by using media queries and adjusting the gallery container’s width accordingly.

@media screen and (max-width: 768px) {
  .gallery-container {
    height: 300px;

10. Testing Across Different Browsers

As with any web development project, it’s crucial to test the image gallery across various web browsers to ensure compatibility. This will help avoid any unexpected issues for users using different browsers.

11. Optimizing Images for Web

Optimizing images is essential for faster loading times and better user experience. Tools like image compression can significantly reduce the file size without compromising image quality.

12. Accessibility Considerations

When creating an image gallery, we must consider accessibility. Adding alternative text (alt text) to each image allows screen readers to describe the images to visually impaired users.

13. Tips for Enhancing User Experience

To make the image gallery more engaging, consider adding features like image captions, hover effects, or auto-play functionality.

14. Common Mistakes to Avoid

Avoid using high-resolution images that slow down loading times, neglecting mobile responsiveness, or forgetting to test the gallery across different devices.


In conclusion, creating an image gallery with a horizontal scrollbar using CSS is a valuable skill for web developers. With the power of CSS Flexbox, we can design an interactive and visually appealing gallery that provides an excellent user experience. Remember to optimize images, ensure accessibility, and test the gallery thoroughly for cross-browser compatibility.


Can I use CSS Grid instead of Flexbox for the image gallery layout?

Yes, CSS Grid is another powerful layout tool that can be used for creating the image gallery. It offers a different approach to positioning elements within a container.

What if some users have disabled CSS or are using an outdated browser?

The image gallery will still be accessible to users with disabled CSS or outdated browsers. They will see a linear display of images, one after another, without the horizontal scrollbar.

Can I combine images and videos in the same gallery?

Absolutely! You can mix and match images and videos within the gallery container, as long as they share the same parent element.

How can I add a lightbox effect to the images in the gallery?

You can implement a lightbox effect using JavaScript or CSS libraries like Lightbox2. This will allow users to view larger versions of the images in a popup window.

Is it possible to have multiple galleries on the same page?

Yes, you can create multiple image galleries on the same page by repeating the HTML and CSS structure with different class names for each gallery.
