I've been doing this for more than a year, and Martin's super help ( I don't dare to bother him anymore

but I am unable to understand how some elements work.
The thing is that I've been creating a skin with a bunch of messy parts
that already cover my needs, the thing is that as soon as I go forward in one part, I go backwards
10 steps on the other side....
SUMMARY
In this link I have an example of the Skin, https://recwind.com/skin/
Hotspots are very important elements for me. But you will see that when you move forward node in the menu
open "info" or other hotspots without closing the previous ones, everything is chaos, elements overlap.
When resizing the popUps, they step on the menu .... etc.
The thing is that all this chaos could be solved if I simply put an image (white for example) below the popUp
so that only appears "Close Icon" and the PopUp and hide the menu and everything in the background ...
I do not know if I understand my problem and could help me

I am a designer if I can help you in something, or if you want to make a skin together...

Thanks to all, specially to Martin
