I am following the horizontal list example at http://css.maxdesign.com.au/listamatic/horizontal16.htm and it looks good, but instead I want to space the list items out throughout the whole area. In other words, each of the five list items should take up 20% of the area, and there should be almost no space between each of the items. How do I do this? I tried setting li's width to 18%, but that didn't work.
