jQuery Forum

I've made my own popup div by toggling the css display of a div from none to block.  I'd like to apply the same styling that the jqm dialog page uses on (data-rel="dialog").  Is there a simple way to go about applying the style or do I need to manually go about it using something like Firebug to copy and paste the css?  (it looks quite complicated in Firebug)

By the way, I'm doing this because the dialog page takes too long to load compared to a simple popup.

Thanks.
