Help plz :) Code for Showing and sliding down at the same time??

Hi people,

first of all I am a pure beginner concerning coding, So I am already sorry if I am asking stupid questions ^^
I was able to code with the examples given here that when i click on a + sign the rest of the text shows up. When I click on the - sign the rest of the text hides. But there for I always needed much space between two paragraphs. So my question ist: I wanna click on the + sign so that the rest of the text shows up and the paragraph below slides down. and when I click on the - sign the rest of the text hides and the second paragraph slides up again.
I’d be happy if someone can help me
