AS3 and CSS

when using the Unordered list in html, i know that when i put a list in a list it will change the way the second bullet looks vs. the first bullet.

In AS3 when using html it does not recognize this. Is there a way that I don’t know of, or am i able to use CSS in the AS3 and will it create a second open sub-bullet?
From what i see, i don’t think i can do this, but am looking for some advice to solve the issue…

Right now, when i put a list in a list…both the first bullet and first sub-bullet look the same.
