How to make the jQuery dialog titlebar transparent

I would like to be able to 开发者_JAVA技巧set the title bar in a jQuery dialog to transparent, I have seen the background being set to transparent but cant see anything on how to do the same to the title bar.

Set .ui-dialog .ui-dialog-titlebar {background-color:transparent}. You may also need to set .ui-dialog .ui-dialog-title {background-color:transparent}
