[flexcoders] Basic CSS question

[candysmate]

I haven't worked much with CSS so please bear with me ...

I have a style set for my Labels with:

Label {
        font-size: 12;
        font-weight: bold;
        font-family: Verdana;
        } 

if I want a particular label to have a different style how do I do this?
I tried styleName="mySpecialStyle" for the label in question without
success.
