title: Remove jQuery UI Dialog Button border/outline
body: <p>Which class do I need to modify/change to remove the outline of a JQuery UI Dialog Button.  I can't seem to figure out which class is applying the border/outline around the 'X' button.  The outline goes away when I click on the button.</p>
