two links with id fdbk_tab breaks the widget

Widget doesn't work when you have two links on a page with the id fdbk_tab.

For example I wanted to have the visible widget on the side of the page along with a link in my footer, both of which would open the overlay. This doesn't work at present as it's triggered on the id.

Can you also separate the css from the js a bit more, by using a class to apply the style and a different class to trigger the overly, instead of using an id?

Thanks
