Large space for questions (CSS)

[Khaireddine Hadj Kacem]

Hi All, 

I try actually to have a smaller distance for questions by mc. The red gap is too big that the questions and answer options are so far apart. The answer options should be in the right side as shown in the screenshot

I tried it with margin (CSS) but that doesn't work. I think that default settings are fixed there. 

Does somebody has an idea. 

Thanks a lot!
