Active Menu Button

[teckn1caLity]

I'm not 100% sure what category this actually goes in so move it if necessary. Here is an image of the hover effect of the button (http://i36.tinypic.com/25zqiom.jpg). How can I make it so the button is automatically pressed down when you are viewing the respective page? The css is below. Any help is appreciated.
