Hello!
How can you track a div block?
There are, let's say, 4 div blocks with the "post" class.
When the mouse scrolls, the block appears and how are objects tracked in jquery at all?

Block appearance in viewport or appearance in DOM?
In the first case, track the scroll and compare the scroll amount with the block coordinates.
In the second - MutationObserver
