Centered Logo

If you want your logo to be positioned in the center of your header please paste this code inside the dedicated area for  Custom CSS Code under the Theme Options Panel:

#logo {
   display: block;
   margin: 30px auto 0;
   float: none;
}
#main-menu {
   margin: 30px 0 35px;
   float: none;
   text-align: center;
   width: 100%;
   padding: 0 !important;
}
#main-menu ul { width: 100%; }
.menu-three .top-menu > li { margin: 0 5px; }

Note that there are some limitations with this position - if you center the logo, the only menu that you can use is the "Classical" menu, since the others don't quite look good.
