Forum How Do You Add New Styles Variables?
 

So I am currently messing around with my VB 4 styles. Editing the variables is easy enough but I ran into a problem I can't find a solution to.

I am trying to add NEW CSS variable to the current style but I don't see where I can do that.

For example* the forum headers have a Width variable built into it already* that I can go in and change* but no height variable. I want to make my forum headers a certain height but I can't find out where to write the new height variable.

How do I go about doing that? Oh and if I am wrong about their not being a height variable* please never mind that. This just an example I am using. I need an answer to where do I insert new style variable to already existing styles.
