Question

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:

list-style: none;
padding: 0;
margin: 0;
background-color:Red

There are a couple issues here.

One, that jsfiddle is all on one line and wrapping.

Two, your CSS for the ul reads: .nav-menu ul — nav-menu IS the ul, thus it should read:

.nav_menu { list-style: none; ... }

The reason the background: red isn’t showing up is because the elements inside of the <ul>, the <li>s have float: left set. This removes from from the flow of the <ul> and effectively makes your <ul> have a height of 0. While there is more than one way to solve this problem, the quickest would be to add a overflow: hidden to the <ul>.
