How can I unactive the them style file

How can I unactive the them style file

Dear Sir,

When I settup jQueryUI I add to add that line
  1. <link rel="stylesheet" type="text/css" href="/cakephp/css/jquery-ui/css/smoothness/jquery-ui.custom.min.css" />

This is fine for the date picker.

But I also use tab and I do not want to use that theme for the tabs.

Here is my simple tabs call
  1. $( ".tabss" ).tabs({
  2.         active: 1
  3.          });

How can I unactive the theme only for the tab .tabss?

Cheers
