He wants that gradient background used as the background for the forum category also! Basically he wants his theme to like like a phpbb theme would look like. This would need to be achieved at template level
It would be pretty easy to do also. Just do this:
find: the CSS for "#latest th, #forumlist th, #favorites th" (in your style.css" file)
Next! Add: "tr.bb-category td" to it so it looks like this:
"#latest th, #forumlist th, #favorites th, tr.bb-category td {"
Note you also will have to remove anything that may reset tr.bb-category td preceding this code.
Hope this helps!
EDIT: P.S CK this is a popular request actually. A large amount people tend to stay away from bbpress because it looks... I really hope someone will take advantage of how bbpress templates are made (with css) and make some sweet themes... All the themes out look the same right now. I'm taking some courses in css and webdeisgn this upcoming semester :p maybe I'll be able to help haha.
Edit 2: I Probably need some grammar classes too lmfao...
