How to Build a "Sticky Stack" Product Page (The Luxury Layout)

By Valkyrie Built | Updated: January 20, 2026

The standard Shopify product page looks the same on every store: A small image carousel on the left, and product details on the right.

If you visit high-end fashion sites (like Acne Studios or Fear of God), you will notice they don't use carousels on desktop. They use a Vertical Stack.

The images are laid out one after another down the page in full resolution, while the "Add to Cart" form sticks to the right side of the screen, following you as you scroll.

This layout (often called the "Sticky Form" layout) increases conversion because the customer sees every angle of the product without clicking "Next" 10 times.

In this guide, we will build this layout using CSS Grid and `position: sticky`.

Step 1: The HTML Grid Structure

We need a parent container that holds two distinct columns: the `gallery` (left) and the `info` (right).

  
  

    {% for image in product.images %}
      
    {% endfor %}
  

  

    
{{ product.title }}
    
{{ product.price | money }}
    
    {% form 'product', product %}
      Add to Cart
    {% endform %}
    
    

      {{ product.description }}
    
  

Step 2: The CSS (Making it Stick)

The magic happens with `position: sticky`. For this to work, the parent container must use `align-items: start` so the columns can have different heights.

/* Desktop Layout Only */
@media screen and (min-width: 990px) {
  
  .product-container {
    display: grid;
    grid-template-columns: 1.5fr 1fr; /* 60% Images, 40% Info */
    gap: 60px;
    align-items: start; /* CRITICAL for sticky */
    padding: 40px;
  }

  .full-width-image {
    width: 100%;
    display: block;
    margin-bottom: 20px; /* Space between images */
  }

  .product-info {
    position: sticky; /* The Magic */
    top: 20px; /* Stops 20px from top of screen */
    height: fit-content;
  }
}

Step 3: Handling Mobile

You do not want a vertical stack on mobile. It would require the user to scroll for 5 minutes to reach the bottom. On mobile, we must revert to a standard slider.

/* Mobile Layout */
@media screen and (max-width: 989px) {
  .product-container {
    display: block;
  }
  
  .product-gallery {
    display: flex; /* Turn stack into horizontal row */
    overflow-x: scroll; /* Enable Swipe */
    scroll-snap-type: x mandatory; /* Snap to image */
  }
  
  .full-width-image {
    min-width: 100%; /* Force full width */
    scroll-snap-align: center;
  }
}

Summary

The "Sticky Stack" layout communicates luxury. It tells the user: "We have high-resolution photography, and we want you to see it."

It also simplifies the User Interface (UI). The "Add to Cart" button is always visible, right next to the image they are looking at.
