Css style sheet question?

I need to create a stylesheet with the following rules:
-All content in the list should be red
-The class "bld" that, when applied, makes the text arial and bolds the text
-The class "shift-ridht" that, when applied, to an anchor tag, moves the text 100 pixels up when the mouse hovers over it
pls help me, it would be so appreciated. THANKS
