dialog : easiest way to hide borders (resizable-handles)

dialog : easiest way to hide borders (resizable-handles)

<div dir="ltr">I would occasionally like to use dialog as (essentially) a light box, which is very easy to do and saves the additional plugins when I'm already using jquery ui.  The one thing I can't seem to figure out is how to hide, or prevent from appearing at all, the dialog resizable-handles that are the border of the dialog.  My basic recipe is:
                $(this).dialog($.extend(this.dialogOptions||{}, {
                    modal: true,
                    resizable:false,
                    height: $(document).height(),
                    width: $(document).width(),
                    overlay: {
                        opacity: 0.2,
                        background: "black"
                    }
                }));<br clear="all">
I've tried modifying the css in firebug to see if I can figure out the css that would need to be modified, but I can't find the right property.
Thanks for any insight.
