Position

[seyedi]

Hi, Can you help me with this please...

Is this statement correct?

If an element is positioned absolutely and none of its predecessors have a positioning context, it is positioned relative to the of the page.

Check this demo which the movement of html doesn't effect the position of our square till html has the position relative.

so I think the element is positioned relative to the page not html.

Thank you so much for your great reference.
