Hello, the question is this:
There is a page body, respectively, and has a scroll bar on the right.
Inside the body there is a div block with overflow: auto, which also has a scroll bar.
When you hover the mouse on this unit and begin to turn the mouse wheel down, then when the end of the scroll the contents of the block starts scrolling the entire body as a whole.
How to disable the body scroll when I scroll the content in the block?
