Floating Side Module Overlapping Bottom Position

Ok thank you. I have added this CSS and now it's at least not covering up the section at the bottom and instead goes underneath it.

However, if the "bottom limit" functionality was working correctly, wouldn't the module ideally stop before it gets to the section below rather than going underneath it?

Just checking in on the question I asked in my previous reply. Let me know if I need to clarify what I mean.

I see that you have put some values for top offset and so on...
Please remove all the offset/position values (just keep the bottom limit) and check how it works. Tell me if this works better

I tried removing the values for offset and it didn't make a difference. Also tried removing the vertical margin and still had the same problem.

I'm still not getting the expected functionality for the "bottom limit" after removing the offset values. Are there any additional troubleshooting steps I can take?

can you give me the FTP access by email ? I need to check in deep what is wrong
