List items format

I am new to Joplin.

I have importet a lot of notes from everest.
The most worked fine, but I have a question about formating text and list items.

In Evernote the list items have no spaces between the lines.
I Joplin they have. So if you have a lot of list items, a lot of space is wasted in my view.

Is there a way to remove the space between the list items lines?

Thank you

I think you should read this forum by "CSS" query. You can find how to use them and some published CSS if you do not want to write your own.

I can be wrong as I am a new user too. But mature users correct me if it so.

When I got you correct, I can create or modify a css file for my own style for the notes?

Where to read more about this?
