Unfortunately the PlugIn does not match the design of my theme, eventhough I checked the "default" box. So I would like to change some design aspects, like font and color. The only answers I could find were older than 4 years and did not work.
For example change the font of the headings as well as the font of the answer-text. I would also like to change the hover colour of the answer-box.

So I would be really happy, if someone could help me with that, please.

Hello,

Could you provide a link to a sample quiz (so we can provide custom CSS styles without conflicts with theme/3rd party plugins styles)?

Hello, thanks for the answer. I managed to change the most important parts of the design now. So it should be fine. Thanks anyway!
