change ul style after applying yui reset + base

[kakiepiroi]

See http://jsfiddle.net/PdZrt/Basically I have applied the yui reset and base and am the trying to seperately style a ul for a menu. The li's pick up the style but the ul doesn't appear too.Any ideas?In the fiddle there should:\[code\]list-style: none;padding: 0;margin: 0;background-color:Red\[/code\]
