Using several tooltips in one document

Using several tooltips in one document

Hi,
I am using several tooltips in one document so I had to change the CSS id-selectors from the links to classes.

But what do I need to do with the id from the file jquery.tooltip.css?
  1. #tooltip {
        position: absolute;
        z-index: 1;...and so on



Do I need to change this as well to produce valid CSS cause it works without changing that but I wanna be sure not having a buggy code?
