[jQuery] no background in BlockUI Plugin

[jQuery] no background in BlockUI Plugin


Hi all,
I am using JQuery BlockUI Plugin..
and I just want to show my loading gif..
but BlockUI Plugin pop-ups has a background color.. and Its not what I
want..
I know we can change pop-ups css..
But is it possible to show just looding gif.. no backgroundColor, no
table color.. just my own gif.
function loading(){
jQuery.blockUI( {message: jQuery('<img src="images/icons/
loading.gif" />'), css:{ backgroundColor: '#ffffff', opacity: '0.7',
color: '#000000', border: '0px solid #a00'} } );
};
thank you all
