Custom Code BB Code

[T3G4Life]

How do i edit the BBcode for the # Code tags,to make it look more flashy? I saw some sites that have custom tags that say (CODE in cool letters and a nice background)

You can edit the bbcode_code template in the style manager.

I saw something on here awhile ago, that was a custom edit with images and so forth, does anyone know about that?
