Your LimeSurvey version: 6.5.5
Own server or LimeSurvey hosting: Own
Survey theme/template: Fruity
==================
We are testing out version 6.5.5 on a fresh install (part of a domain migration), currently using 5.6.35.

We have noticed that regardless of theme we use, the CSS class is half working when displaying the question. We want to have for example 3 text answer questions in a row, for these we have set the CSS class in the display options to "col-sm-4, col-md-4, col-lg-4" on each and whilst they are resizing they are not sitting side by side.

Any advice would be greatly appreciated.

@andrlewis we don't really need IA answers.
