Hide Scrollbars but still scrollable

Hi,

in my sidebar i have a scrollable container which is showing me the categories from my database.
How i can remove/hide the scrollbars without effecting the scroll of the container.

-webkit-scrollbar is not working for me

or it will be gone when i publish the web app?
I can not really test it since i have deleted the project with my subscription and now i really have to pay again for the other project, it was just few days ago? -.-

TLDR you only see it in the published version

Removing scrollbars is a very bad practice in terms of UX. Please don’t do it.
