Howdy, Trying to change the colour of the active page

Howdy,

Trying to change the colour of the active page highlight bar (http://tiny.cc/menuhighlight)
on this site:
http://staging1.websitesforhippies.com/

I know it's this CSS, but I can't get the syntax correct: x-navbar .x-nav > li > a:hover, .x-navbar .x-nav > .current-menu-item > .a box-shadow

Thanks,
Casper
