Is it possible to set the width of a survey to 800 px (the distance of the left and right border of the container = 800 px). I understand that this maybe can be set in the custom.css file of the template somehow? If the width can be set to max 800 px, instead of fixed to 800 px that's even better.
I've found answers for older versions of LimeSurvey, but they did not work.
