I\'m looking to create a navigation menu with list items rendered in one line. How do I do this?
One of the best resources on the subject is http://css.maxdesign.com.au/listamatic/ (a little outdated though).
They suggest both li {display: inline;}
and li {float: left;}
depending on the effect you want.
Look for example their "Simple horizontal list" http://css.maxdesign.com.au/listamatic/horizontal01.htm
ul {display: inline;}
ul li { list-style: none;display: inline;}
