How to move also the language selector boc and the move on arrow when making

Hello, 

I want to make the whole screen full with my survey question, therefore I use this code in “Look & Feel”.

However, I struggle as the language selection and the “move on” button are not spaced out with the text. See picture.

Here is my CSS:

.Skin .SkinInner {width: 80% !important;}
.Skin .QuestionBody{ max-width: 60% !important; }
.Skin .QuestionText{ max-width: 60% !important;}
