External CSS

[voja]

Hi,

I use ExtEvent to style components, for example this is code:

 

function OnAfterrender(sender)

{

sender.body.applyStyles('background-image:url("files/images/background.jpg"); background-repeat:repeat-x; background-color:#f2f2f2;');

}

 

My question is:

How I call these style from custom css (external file)????

 

Thanks
