Text alignment in horizontal drop down menu

Q: I have created the menu, but I'd like to change the text alignment in the submenu.
Where I can do that?

A: Please, open the generated .css file in any text editor and find the code:

ul#css3menu1 ul a {
    background-color: #5F181B;
    background-image: none;
    border-color: #293344;
    border-radius: 0 0 0 0;
    border-style: solid;
    border-width: 1px 0 0;
    color: #FFF8AF;
    font: 13px Arial;
    padding: 8px 0 0;
    text-align: center;
    text-decoration: none;

Change "text-align" parameter.
