webkong on "Navigation (Hustle)"

I am trying to make the boxes around my navigation menu shorter instead of going all the way from the top I already reduce the padding (between the header and body) and changed the color of the menu but I cant see how to adjust the height. I would like to make them hald of what they are now. sunshineinteational.us

#navigation ul.nav > li > a {
    padding: 2.236em 0.618em;
    border-top: 5px solid transparent;
}

Change padding to half. Add to your custom css.
