Mobile Friendly single answer choice show answer side by side

Hi
I try to figure out how to show the single answer choice side by side instead of vertically. I have already set the position as horizontal on the question level. However, the mobile friendly preview is still show as vertical. Can I set css in the look and feel for this? I have been playing with this but no luck. Thanks

padding-top: 20px;

padding-bottom: 20px;

padding-left: 200px;

padding-right: 70px;

margin: 1;

border: 1;


}
