Adding a line break or space in TWIG
In the Twig documentation, there is an entry that can help you out: https://twig.symfony.com/doc/2.x/filters/nl2br.html

{{ "I like Twig.\nYou will like it too."|nl2br }}


will output:

I like Twig.&lt;br /&gt;
You will like it too.


So inside a string, you could use \n or the function nl2br at the end of it.
