[SOLVED] auto-hide topbar

I would like to auto-hide the top-bar, so I don't have to see it all the time.

I am using: Debian GNU/Linux 10 (buster)

any idea?
thanks.

looks like there is an extension: https://extensions.gnome.org/extensi.../hide-top-bar/ (but probably there are others)

OP: assuming you are using Gnome? You didn't mention which window manager or desktop environment and there are dozens of them.
