How can I debug my Intersection Observer implementation?

I'm having trouble with my Intersection Observer. It doesn't seem to trigger when elements come into view.

Let's troubleshoot that! Can you share your Intersection Observer code and the conditions under which it's not triggering?

Sure! Here's my code: const observer = new IntersectionObserver(callback, options); I set the root margin to '0px'.

Thanks! Check if the target elements are actually within the viewport. Also, ensure that the callback function is defined correctly.

I think the callback is fine. The elements are in the viewport, but still no trigger.

In that case, verify the options you passed to the observer. Sometimes, the threshold can affect when the callback is called.
