# Sticky add to cart

The Sticky add to cart block ensures your customers can always access the "Add to Cart" button—no matter where they are on the product page. When the main Buy buttons block is out of view, this sticky bar appears either at the top or bottom of the screen, helping reduce friction and improve conversion.

*<mark style="color:red;">(screenshot)</mark>*

### Settings:

{% hint style="info" %}
**Note**: The sticky Add to Cart bar appears when the regular **Buy buttons** block is out of view.\
When customers click this sticky bar, the page automatically scrolls down to the full **Buy buttons** block.
{% endhint %}

* **Sticky position:**
  * **Top:** Appears below the header and announcement bar (or at the top if those are not present).
  * **Bottom:** Appears at the bottom of the screen.
* **Devices:** Specifies which devices will display the sticky button: Mobile, Desktop or all devices.
* **Mobile layout settings:**
  * **Show cart total:** When enabled, the total cart value (e.g., "$75.00") will appear beside the **Add to cart** label inside the sticky button on mobile.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.byinspiredlabs.com/product-page/product-information/sticky-add-to-cart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
