Guide to Replace `#block-id` for Confetti Animation:

Locate the Block ID of Your Button:
- Open your Squarespace website in a browser.
- Right-click on the button you want to trigger the confetti animation and select Inspect or Inspect Element.
- Look for a parent element or the button itself with an id attribute. It will look something like id="block-yui_3_17_2_1_1728728185968_2536".
Copy the Block ID:
- Highlight and copy the id value (e.g., block-yui_3_17_2_1_1728728185968_2536).
Replace the Existing Block ID in the Code:
- Locate the line in your JavaScript code where the button selector is defined:

How to add Confetti Pop! Buttons in Squarespace 7.1

Replace #block-yui_3_17_2_1_1728728185968_2536 with the copied Block ID from Step 2.

Verify the Button Class:
- Ensure that the .sqs-block-button-element class is still valid for your button. This class is commonly used for buttons in Squarespace but may vary depending on your template or custom styles.
- If your button uses a different class, update the selector accordingly, e.g., #your-block-id .your-button-class.
Test the Confetti Animation:
- Save the updated JavaScript code and refresh your website.
- Click the button to ensure the confetti animation triggers as expected.
- If it doesn’t work, double-check the Block ID and the button’s class.
Optional: Watch for Dynamic Changes:
- If your button is dynamically loaded (e.g., part of a popup or AJAX-loaded content), the provided script includes a MutationObserver to detect changes in the DOM. No further action is required to handle this unless you need to customize the observer
