On Drupal 8 site using the default Bartik theme, I have setup the article content type to be displayed in horizontal tabs based on the "field group" module.
On normal/large screens, the article display page is rendered in horizontal tabs style (Good!):
However, in small screens, the article display page is rendered in accordion style (Not good!):
I have found an answer here Horizontal Tabs rendered as rendering collapsible fields which is for Drupal 7 and I didn't know how to convert it to work for Drupal 8.
Does anyone have an ideas how to keep the article display rendered as horizontal tabs for whatever screen sizes?
