How to Add a Sticky Add to Cart to the Horizon Theme

One of the biggest conversion killers on mobile is a hidden "Add to Cart" button. When customers scroll down to read your product description or reviews, the buy button disappears, forcing them to scroll all the way back up to purchase.

The solution is a Sticky Add to Cart bar that stays fixed to the bottom of the screen. In this guide, we’ll show you how to add this essential feature to the Horizon theme using the Section Store app—no coding required.

Step-by-Step Guide

Follow these steps to keep your buy button always visible:

1. Open the Section Store App: If you haven't already, install the Section Store app on your Shopify store.
2. Navigate to Conversion Blocks: Inside the app, click on the "Conversion Blocks" tab. This category contains sections specifically designed to boost sales.
3. Select the Sticky Cart: Locate the "Sticky Add to Cart" block. Click on it and select "Add to Theme," choosing your active Horizon theme.
4. Customize in Theme Editor: Go to your Shopify Theme Editor (Online Store > Customize). You will see the Sticky Add to Cart section added to your product page.
5. Style It: Click on the block to adjust the settings. You can match the button color to your brand, choose when it appears (e.g., only after scrolling past the main button), and ensure it looks perfect on mobile.
6. Save: Hit Save to publish the changes. Your customers will now have a one-click checkout option no matter where they are on the page.
