Misplon on "[Theme: Vantage] Right Align Nav-Bar"

My bad! Rather use the selectors I just gave now. If you need to center the menu then you'd say:

/* Vantage right align the main menu */

.main-navigation ul {
font-size: 0;
text-align: center;
}

.main-navigation ul li {
display: inline-block;
float: none;
font-size: 13px;
}

.main-navigation ul ul li {
text-align: left;
}
