Adopt theme settings to have fullwidth color sections / all other elements boxed

Dear all,
I would like to change the layout of our website https://www.deuta-controls.net just a little bit.
What I would like to have is to leave everything as is, but to have full-widht color sections instead of a boxed design for them.
So, at the end, the same look as https://kriesi.at/themes/enfold/
Actually I use “Boxed Orange” with some little modifications, so layout is perfect for all the contents.
But I did not find the way how to change the parameters to have only color sections as non-boxed elements.
Hope I am clear, and somebody can help.
Kind reagrds from Germany,
Michael
