I'm using moodle 3.3 and default MORE theme.
I'd like to customise forumposts such as changing userpicture = avatar's width and height (60px), changing background color and height and so on. In a word, I'd like to customise forumposts somewhat like moodle.org
+ Forumpost in my site (blocks on the left)
+ Forumposts in moodle.org
Thanks in advance,
