By default, the logo is placed on the left and the menu links are placed on the right of the primary menu. With this code snippet you can reverse this order.

/* Move the logo in the primary menu from left to right*/
#et-top-navigation {
   float: left; 
   padding-left: 0 !important;
}
.container .logo_container {
   text-align: right;
}
