Introduction
Mobile user experience is crucial in today's e-commerce landscape. With a significant portion of online transactions happening on mobile devices, ensuring a seamless browsing experience is more important than ever. Magento 2.3, a leading e-commerce platform, allows users to incorporate various features and functionalities to enhance user experience. One common issue faced by developers is the smooth scroll functionality for Fotorama galleries on mobile devices. The default behavior often feels choppy, leading to a less-than-ideal user experience.
In this guide, we will dive deep into addressing this issue, providing a step-by-step approach to improving the smooth scroll of the Fotorama gallery navigation on mobile devices. By the end of this post, you will have a comprehensive understanding of how to optimize this feature for a seamless mobile browsing experience.
Understanding the Fotorama Gallery
Fotorama is a highly popular gallery plugin used by many Magento 2.3 stores to create responsive image galleries. It offers a great deal of flexibility and customization options, making it a go-to choice for developers. However, despite its robust functionality, the default scrolling behavior on mobile devices can sometimes be less than smooth, affecting the overall user experience.
The Problem with Mobile Scroll
On mobile devices, the issue manifests as a jerky or choppy scroll within the gallery navigation. Typically, this occurs due to the default scrolling increment being set to a small value (around 20-30px), which does not provide a smooth transition when users swipe through thumbnails.
Why Smooth Scrolling Matters
Smooth scrolling is not just about aesthetics; it significantly enhances the user experience by making navigation intuitive and fluid. In e-commerce, where user experience directly impacts conversion rates, optimizing such seemingly minor details can lead to substantial improvements in user satisfaction and, ultimately, sales.
Implementing the Solution
To address this issue, we need to make some modifications to the Fotorama JavaScript file. Here’s a step-by-step guide to achieving smoother scrolling behavior.
Step-by-Step Guide
1. Locate the Fotorama Script
First, we need to locate the fotorama.js file within your Magento 2.3 installation. This file is responsible for the behavior and functionality of the Fotorama gallery.

2. Identify the Relevant Function
Open the fotorama.js file and locate the following function:
jQuery.Fotorama = function ($fotorama, opts)
Within this function, we need to find the section that handles touch events on the gallery navigation. Look for the navShaftTouchTail variable and the onEnd function block.
3. Modify the Scroll Behavior
Within the onEnd function, modify the scroll behavior to provide a smoother experience. Here’s how you can do this by adjusting the position parameters:
const pos = result.newPos < result.pos ? result.newPos - 75 : result.newPos + 75;
This adjustment ensures that the scroll increment is increased, thus making the scrolling action smoother and more responsive.
Example Implementation
Below is an example of how the changes might be applied within the fotorama.js file:
jQuery.Fotorama = function ($fotorama, opts) {
// Existing code
var navShaftTouchTail = moveOnTouch,
var onEnd = function () {
// Other conditions
if (result.pos !== result.newPos) {
const pos = result.newPos < result.pos ? result.newPos - 75 : result.newPos + 75;
slide(pos); // Modified slide function parameters
}
};
// Rest of the code
};
4. Testing the Changes
After making these changes, it's essential to test the gallery on various mobile devices to ensure the scroll behavior is smooth and responsive. This can involve both manual testing and using mobile emulators to validate the improvements.
Additional Tips for Smooth Scroll Optimization
Optimize Images
Ensure that the images used in the Fotorama gallery are optimized for web use. Large, unoptimized images can cause lag and affect the smoothness of the scroll.
Use a Content Delivery Network (CDN)
Implementing a CDN can significantly improve loading times and performance for users accessing your site from different geographical locations. Faster loading times contribute to a smoother overall experience.
Minimize JavaScript Conflicts
Ensure that there are no conflicting JavaScript files or libraries that might interfere with the Fotorama functionality. Conflicts can result in erratic behavior and uneven scrolling.
Conclusion
Improving the smooth scroll functionality of the Fotorama gallery on mobile devices in Magento 2.3 is a straightforward process that can greatly enhance user experience. By modifying key parameters within the fotorama.js file, you can ensure a fluid and responsive scroll action that will delight mobile users.
In addition to code modifications, considering broader performance enhancements like image optimization and CDN implementation can contribute to a smoother browsing experience overall. With these improvements, you can provide a top-notch user experience that keeps visitors engaged and increases the likelihood of conversions.
FAQs
Q: Will these changes affect the desktop version of the gallery? A: No, the modifications specifically target the touch events used in mobile navigation, so desktop behavior should remain unaffected.
Q: Can I revert these changes easily?
A: Yes, you can revert to the original fotorama.js file or make a backup before making edits. Simply replace the modified file with the original to roll back changes.
Q: What if the smooth scroll still isn't perfect? A: Further adjustments to the scroll increment value or additional testing on different devices might be necessary. Ensuring other JavaScript optimizations and reducing load times can also help.
Q: Are there plugins or extensions that can help with this? A: While manual adjustments as described are effective, some third-party Magento extensions offer enhanced gallery features and might address similar issues more comprehensively.
By following this guide, you can significantly improve the smooth scroll functionality of your Fotorama galleries, providing a better user experience for mobile visitors to your Magento 2.3 store.
