Tish " I have a lot of cloze questions in my courses, and I use a smaller text size for the questions for 2 reasons.
1 - so as the person creating & editing the questions, I can easily identify the question amongst the text. (see pic below & attached)
2 - because the drop-down menu box appeared (in 2.5) quite tall compared with the rest of the text, I found that by reducing the font size, it also reduced the size of the drop-down menu box and fitted in much more nicely with the rest of the text."
Reason #1 can be quite useful when editing quesitons.
However, Reason #2 did work in Moodle 2.5 and 2.6, using Standard Theme. But it no longer works in Moodle 2.7 using "standard" Clean theme (Bootstrap based). Maybe it's no longer necessary?
