is the correct property. I would imagine you're either using the wrong selector. If the  changes are working you can safely discount this.

The other option is that there is a more specific selector overriding your CSS. To get around this, you can either duplicate the selector which you can find this by looking in Chrome's inspect element or Firebug for Firefox (or your choice of CSS rule inspector), or by adding  to the value for.

I'd recommend using the first option, it makes CSS easier to maintain. should only really be used as a last resort.
