Sticky Add To Cart Element

As a GemPages user,
I want a sticky Add To Cart button that remains visible as the shopper scrolls down the product page,
So that it's easy for customers to add items to their cart without needing to scroll back up, leading to a smoother shopping experience and potentially increasing conversion rates.

Acceptance Criteria:

1. Visibility While Scrolling: The Add To Cart button becomes sticky (i.e., fixed position) and remains visible on the screen when the user scrolls past the original location of the button on the product page.

2. Customizable Appearance: Users can customize the look of the sticky Add To Cart button, including its color, text, and size, to ensure it matches the overall design of their website.

3. Responsive Design: The sticky Add To Cart button is fully responsive and adapts to different screen sizes and devices, ensuring a consistent and accessible shopping experience across all platforms.

4. Integration with Product Options: When a product has options like size or color, the sticky Add To Cart button should reflect the selections made by the customer as they scroll. It should update in real time if the customer changes their selections.

5. Animation and Visibility Control: Users can control the animation of the sticky button as it appears or disappears and set conditions for its visibility (e.g., only after the user has scrolled a certain percentage of the page).

6. Performance Optimized: The implementation of the sticky Add To Cart button should not significantly affect the page's loading time or performance.

7. Easy Activation: Users can easily enable or disable the sticky Add To Cart feature from the GemPages dashboard without the need for custom coding.

8. Compatibility Check: Ensure that the sticky Add To Cart button is compatible with all major browsers and does not interfere with other page elements or functionalities.

Notes:

• The feature should prioritize mobile users, given the importance of mobile commerce.

• Consider accessibility best practices to ensure the button is usable by everyone, including people with disabilities.

• The sticky Add To Cart button should be tested with various themes and custom layouts to ensure compatibility.
