Skinning the Menu widget is done using CSS. The stylesheet used for other Menu examples is a minified version of the menu-core.css and menu-skin.css files. When customizing the Menu skin, use the raw source files as a reference.
The menu-core.css file includes foundational styling that controls basic layout and positioning, whereas the menu-skin.css file is used to apply colors, borders, padding, etc. Skinning can be accomplished by either overriding the styles defined in the menu-skin.css file, or by creating an entirely new skin file. When overriding styles, place them in a separate file to simplify integrating with YUI updates. The follow example illustrates how to override some of the default styles defined by the "Sam" skin.
