RTL tabs

Hi fellas,
I have a Rtl site, and i want my tabs headings to be from right to left and not the other way around as the default,
what is the currect css for that?

(for example, tab 1 is float right and the first to appear, and every other tab shall be at the left of that tab and not on the right.)

thank u.
