It looks like vb4 moved a lot of things to the bbcode.css template. What you could probably do is add a section to additional.css like this:

.bbcode_container {
// your CSS here
}

And override the existing CSS with whatever you want. You might also be able to copy the vb3 bbcode_code template to vb4, but you would have to update the variable references to vb4 template syntax (assuming those style variables still exist in vb4).
