How do I get those values? I see the example on the YUI page to do this but using a click event, and then calling the get('winWidth') method on the event target. But how can I get these values without the use of any event? Thanks

            Simply
YAHOO.util.Dom.getViewportWidth();
YAHOO.util.Dom.getViewportHeight();
keep in mind you can reduce YUI namespace as shown bellow
(function() {
    var Yutil = YAHOO.util,
         Ydom = Ytil.Dom;
    Ydom.getViewportWidth();
    Ydom.getViewportHeight();
})();
