Introduction

Shopify’s Minimal theme is popular for its clean and straightforward design, but many users find its default mobile gallery layout challenging, especially when displaying multiple images for a single product. The layout requires users to scroll vertically, which can be tedious on mobile devices. This guide will help you create a horizontal scrolling gallery optimized for mobile, ensuring a smoother browsing experience for your customers.

1. Issues with the Minimal Theme Gallery on Mobile

By default, Shopify’s Minimal theme displays product images in a vertical stack on mobile, which can be cumbersome for users. Here are some common issues merchants encounter:

• Long Scrolling: Users must scroll through each image, which can be frustrating if there are many product images.
• Lack of Horizontal Navigation: The theme doesn’t allow for easy horizontal navigation, which is more intuitive for mobile.
• Inconsistent Image Sizes: If images vary in size, the gallery may appear unbalanced, impacting visual appeal.

2. Benefits of Optimizing the Gallery for Mobile

A responsive, horizontally scrolling gallery enhances user experience, especially for mobile shoppers. Key benefits include:

• Improved User Experience: A smooth, swipeable gallery aligns with mobile browsing habits, making it easier for users to explore images.
• Reduced Scrolling Time: Horizontal scrolling reduces the need for excessive vertical scrolling, making the gallery faster and more engaging.
• Enhanced Aesthetic Appeal: Consistent image sizes and easy navigation improve the overall look and feel of the product page.

3. Steps to Create a Horizontal Scrolling Gallery

Follow these steps to set up a horizontal scrolling gallery for the Minimal theme on Shopify. This customization requires some CSS and HTML editing, so it’s best suited for those comfortable with code adjustments.

4. Modifying CSS for Horizontal Scrolling

In your Shopify admin:

1. Go to Online Store > Themes and click on Customize.
2. Select Edit Code under Actions for the Minimal theme.
3. Under Assets, open theme.scss.liquid. Add the following CSS code at the bottom:

        {% raw %}
        /* Horizontal Scrolling Product Gallery */
        {% assign product_gallery_columns = 4 %}

        .product-gallery-container {
            display: grid;
            grid-gap: 4px;
            grid-template-columns: 4px 1fr 4px;
            overflow-x: auto;
            scroll-snap-type: x mandatory;
            padding-bottom: 4px;
        }

        .product-gallery-container ul {
            display: flex;
            flex-wrap: nowrap;
            padding: 0;
            margin: 0;
            list-style: none;
        }

        .product-gallery-item {
            scroll-snap-align: start;
            flex: 0 0 calc(100% / {{ product_gallery_columns }});
            display: flex;
            justify-content: center;
            padding: 4px;
        }

        .product-gallery-item img {
            border-radius: 8px;
            width: 100%;
            height: auto;
            object-fit: cover;
        }
        {% endraw %}
    

Feel free to adjust the product_gallery_columns variable to change the number of images shown at once. Save the changes when done.

5. Updating Product Template to Display Horizontal Gallery

Next, update the product-template.liquid file to use this horizontal layout. Follow these steps:

1. In your theme editor, go to Sections and open product-template.liquid.
2. Locate the section where the product images are rendered. It typically looks like:

            {% raw %}
            {% if product.images.size > 1 %}
                

                    {% for image in product.images %}
                        

                            
                                
                            
                        
                    {% endfor %}
                
            {% endif %}
            {% endraw %}
        

3. Replace this code with the following modified code for horizontal scrolling:

            {% raw %}
            {% if product.images.size > 1 %}
                

                    

                        {% for image in product.images %}
                            

                                
                                    
                                
                            
                        {% endfor %}
                    
                
            {% endif %}
            {% endraw %}
        

Save your changes and preview the product page to see the new horizontally scrolling gallery on mobile.

6. Enhancements for Better User Experience

To further improve usability, consider these enhancements:

• Add Navigation Arrows: To guide users, add arrows on either side of the gallery. Use CSS to position the arrows outside the scrolling area, or add a small JavaScript function for easier navigation.
• Standardize Thumbnail Sizes: Ensure all thumbnails are consistent. Modify the product template to center-crop images if they have varying aspect ratios by adding crop: 'center' to the image URL.
• Lazy Loading: If your gallery has many images, consider adding lazy loading to improve page load speed.

Conclusion

Optimizing the Shopify Minimal theme’s gallery for mobile provides a significant boost to user experience by making navigation faster and more intuitive. By implementing a horizontal scrolling layout, you improve the aesthetic and functionality of the mobile product page, which can lead to higher engagement and conversions. Follow these steps to give your mobile shoppers a seamless browsing experience.
