Owner only view of breadcrumb

Cygnus Studios

Is it possible to have an owner only breadcrumb trail?

In the legacy site I had the following:

#homepage #breadcrumb {
display : none;
}
#breadcrumb {
visibility : hidden;
}
.loggedIn #breadcrumb {
visibility : visible;
}
#altViews {
visibility : visible;
}

I have tried different combinations with the code in the new site, but nothing I've come up with works.
