Probably an obvious beginner question: I'm looking for an easy way to style standard HTML ordered lists without any tags like the following hierarchy:
A. One
    I. Two
        1. Three 
            a. Four
                aa. Five
                    (I.) Six
                        (1.) Seven 
                            (a.) Eight
                                (aa.) Nine
Is there a CSS solution for this? According to my "research" the custom stylings for levels Five to Nine can only be achieved with CSS counters?
