Hello, I use horizontal menu with list-item elements on my site. It works good in IE/Win 5+ but behaves strange in Mozilla and Opera. I can't figure out why the content overflows its right border and why the height of a parent box is miscalculated. The site is in Czech. I'm sure it won't be problem for you.
