Comments: Depending on the font you use, you may need to adjust the negative margin-top inside #navcontainer ul. I made no use of the #navlist or #active, but put them there for consistency.
ABOUT THE CODE
Some lists within the Listamatic site had to be modified so that they could
work on Listamatic's simple list model. When in doubt, use the external
resource first, or at least compare both models to see which one suits your needs.
