CSS: Moving the text down a few pixels but keeping the background still?

Question

I have some CSS buttons that are bigger when hovered over. I have also made the text bigger however I would like to move the text down a few px without messing with the background image being used.

help?

my code looks like this:

<div id="nav">
    <a href="index.php">Home</a>
    <a id="headrush">Beer Bongs</a>
    <a id="thabto">Novelty</a>
</div>

#nav a {
    background: url(Images/Button.png);
    height: 28px;
    width: 130px;
    font-family: "Book Antiqua";
    font-size: 12px;
    text-align: center;
    vertical-align: bottom;
    color: #C60;
    text-decoration: none;
    background-position: center;
    margin: auto;
    display: block;
    position: relative;
}

#nav a:hover {
    background: url(Images/Button%20Hover.png);
    height: 34px;
    width: 140px;
    font-family: "Book Antiqua";
    font-size: 16px;
    text-align: center;
    color: #C60;
    text-decoration: none;
    margin: -3px;
    z-index: 2;
}

#nav a:active {
    background: url(Images/Button%20Hover.png);
    height: 34px;
    width: 140px;
    font-family: "Book Antiqua";
    font-size: 14px;
    text-align: center;
    color: #862902;
    text-decoration: none;
    margin: 0 -3px;
    z-index: 2;
}
