In quiz questions it looks like the specific CSS rules are not correctly applied in the Moodle app. For instance, with a GapFill question inside a quiz we can see that the rules are:
- OK on a website
- only half OK on the Moodle App on an Android tablet
- not OK at all in https://mobileapp.moodledemo.net/
This is problematic when developing in mobileapp.moodledemo.net/, as we can't see the correct results. As far as I can remember those specific CSS rules used to work there.
