How far is the option to change, fontsize and color?

Hi Josh,
a “quiz designer” will be introduced in the next major release – but that is months away.

For now, the easiest way to custom style your quizzes is by adding some simple CSS to your theme’s style.css file

To change the question size and colour

.h3.hdq_question_heading {
   font-size: 22px !important;
   color: #000000 !important;
}

To change the answer size and colour

.hdq_label_answer {
   font-size: 22px !important;
   color: #000000 !important;
}
