A great way to improve page user experience is to ensure customers can quickly move to the top of a page. So, no matter where they are on a page, they can find their way back without having to scroll up again.
A Back to Top button is really helpful if you have long pages that need a lot of scrolling. By clicking this floating button located somewhere on a page, customers can now return to the top of said page.
In this tutorial, you’ll find a detailed walkthrough on how to add a Back to Top button to your Shopify store using code.
How to Add Back to Top Button using Code
From your Shopify admin, go to Online Store > Themes.
- Find the theme you want to edit, and then click Actions > Edit code.
- In the Snippets directory, click Add a new snippet.
- Name your snippet back-to-the-top, then click Create snippet. Your snippet file opens in the code editor.

{% comment %}
Vertical offset from bottom of browser for the position of the button.
{% endcomment %}
