The distance is obviously not constant. It probably depends on the height of the items on my sitebar.
Have a look here: https://psplm24.de/werbung-content-partner/
and for comparison here: https://psplm24.de/nice-to-know/siemens-nx-environment-variables/
I also noticed that the value “Top” (HTML/CSS) doesn’t fit. As long as the block has the value “position: static” the value “top” is 147px (so far everything is fine).
If the scrolling starts, the value “top” changes dynamically (I think that’s correct so far). However, as soon as I reach the lower third while scrolling (felt when the footer appears)
the value “top” falls clearly into minus and ends up at “top: -1416.84px”. If I manually set the value for “top” to “top: 0px) at the end of the scrolling, everything looks correct.
I hope this helps…
