How to make a whiteline/line break in card description?

[Balder]

I am trying to do one of the most basic things in writing text. A white line on a Trello card description. I am sure there is a simple solution that I should have easily managed to find. But I can't find it. I have googled, Trello markdown explanation didn't give it to me. Official markdown solutions didn't work in Trello. And StackExchange solutions suggested for Trello didn' t work either. Can anyone help me ?

Thanks in advance and have a nice day everyone,
Balder

You can make a line break by putting three or more dashes ("---") on its own line (with no text immediately above it).

Here's what it looks like while editing:

Then when you hit save, it should look like this:

The color of the line depends on your browser.

Thanks, that will work :) (and it does.)
I realize now what I was mostly looking for is called a blank line, not whiteline. However this line break looks pretty good too.
