How to wrap admin menus and menu headers in additional divs without modifying the WordPress core?

I need to do this to enable advanced styling options via css, the one a class the headers are wrapped in isn’t adequate to do the type of styling needed. Thanks!

Since the admin back-end menus do have li tags you can use that if you want. but as far as adding divs you will need to hack the core files directly. That is if you are talking about the back-end.
