We run discourse since 2017 as a Q&A community but we are trying to change the design to make the website looks like a Q&A community more than a forum.
any ideas?
What “functions” are you expecting from a “Q&A” community? Do you mean something in particular?
Are you looking for a voting system? I think there’s a plugin for that! 
Hello, no only from the design, we need to change the design to make it look like yahoo answers, stack overflow or even quora.
give the user impression of Q&A community more than a discussion forum.
Discourse가 이미 요청하신 용도에 부합한다고 생각합니다… 
일부 플러그인을 사용하면 사용자 경험을 더욱 풍부하게 만들 수도 있습니다! (투표 시스템, 해결책 표시 등)
혹시 특정 디자인을 찾고 계신 것일 수도 있습니다. Customization > Theme 채널을 확인해 보시기 바랍니다!
If you want a full QA experience you can use some other software that is aimed at QA. There are multiple Stack overflow clones, or you can also go and buy Stack Overflow for teams.
Discourse is awesome, flexible and secure.
you don`t believe me if i say i was looking for stack overflow clones 3 years ago when i found discourse.
all we need just to change the design not the functions.
직접 커스텀 테마를 작업해서 상상하는 모습에 더 가깝게 만드는 게 좋을 것 같아요. Customization > Theme 채널에서 참고할 수 있는 예시들이 많이 있습니다.
Fedora Project has a dedicated Discourse installation for Q&A. Have you seen it yet?
In terms of appearance,Quora looks like the Facebook Discourse theme:

We now have the Post Voting plugin that allows replies to be voted on and reorders the topic to show the highest rated towards the top. This can be really useful for a Q&A format.
