Hi, Try adding the "yui-skin-sam" class to the BODY element. If you're renderin= g the Dialog container to document.body, then adding the yui-skin-sam class= to an ancestor DIV of the button which pops up the Calendar won't apply th= e skin correctly (which appears to be what's happening), since the Dialog/C= alendar are not actually rendered as children of that DIV. Regards, Satyen ing page's content. Firebug shows no errors and things seem to run OK, but the rendering isn't = quite right, i.e. the calendar background (off-white) isn't displaying and = I can see through to my site's native background color. Saying it another way, it's like the calendar background is transparent. I = also don't see any navigation arrows or buttons on the calendar. What I do see are the actual numbers that represent the days of the month o= verlaying my page as well as the calendar header (month name/year), but no = calendar background color or calendar buttons/images. I'm using YUI 2.7.0 and the links to the Yahoo CDN from the config builder = helper: <!7.0/build/dragdrop/dragdrop-min.js&2.7.0/build/container/container-min.js">= </script> I've added 'class=3D"yui-skin-sam"' to a top level div in my page that's a = grandparent/ancestor of the button that shows the pop-up calendar. It appears that the sample code from that example dynamically inserts a div= with an id of "cal" somewhere to handle the actual calendar rendering. The only other thing I knew to do from looking at some other posts was to c= heck the CSS for the "calnavleft" and "calnavright" image paths and did see= something odd: <thead> <tr> <th class=3D"calhead" colspan=3D"7"> <div class=3D"calheader"> <a class=3D"calnavleft" href=3D"#">Previous Month (March 2009)</a> April 2009 <a class=3D"calnavright" href=3D"#">Next Month (May 2009)</a> </div> </th> </tr> <tr class=3D"calweekdayrow"> ... </tr> </thead> Notice the "#" URI's for the nav classes. Sorry for the long post. I'd really appreciate any suggestions or hints. Thanks, -Eric
