I see. That mean I need to edit the css of comment box in my website.
Maybe it too much, but what kind of css I need to change in this case, just for the quote comment box is in right orders and positions? In the case this request is out-topic, I am sorry, just ingore it.
Also, the WP Discourse seem only working on singe post page of Wordpress, since it doesn’t give me optional when create a Page. Is it true or just problem in my website again?
