In Markdown, you want to put two spaces at the end of a line if you don’t want it to be treated as a single rewrapped line.
So:
foo
bar
Gives
foo bar
And with two spaces after “foo”:
foo
bar
I generally use bulleted lists instead to make it clear that it’s a list.
* *00: Space Marine*
* *Call of Duty: Black Ops*
Gives:
- 000: Space Marine
- Call of Duty: Black Ops
The blank line between the two actually – well, I suppose some clients might act differently than others, but certainly in the Web UI on lemmy and IIRC Reddit – produces a different effect, has a larger horizontal space, and is intended to be a paragraph break rather than just a line break.
(with two spaces trailing “foo”) Gives:
foo
bar
And
Gives:
foo
bar
It’s not normally a massive difference, but suppose you’re writing poetry, say, you’d probably rather have paragraph breaks between verses and line breaks after each line in a verse:
