Separate background lines

[bryonyn43458730]

Hello, 
I would like to know if there is a way to  the lines (So there is a visible white line in-between each line, like on photo 2) on the background color with a soft return and not a hard return?

(Firstly: you are using the terms hard return and soft return incorrectly).

You could recreate the blue background by setting a wide superscript underline in the paragraph style.

Disadvantage: an additional space is required before the first and after the last word of each line.

C'est possible en utilisant des filets de paragraphe (un filet au dessus et un autre en dessous)
