How to hide part of a page enclosed with div tags from logged in users?

Hello!

I have an introduction to my site on a static page, but I would like to hide it once a user is logged in.

I’ve little experience in codding. I’ve tried to use the “if user logged in function then… else”, but I was unable to get it work.

Could you help me by providing possible solution? What code could I use, where to put it?

Regards!
Tom
