gistfile1.js

var GalleryRouter = Backbone.Router.extend ({
    routes: {
        '*actions': function(action) {
            id = '#' + action;
            jQuery(document).ready(function($) {
                $("html, body").animate({ scrollTop: $(id).offset().top -150 }, 1000);
            });
        }
    }
});

var appRouter = new GalleryRouter();
Backbone.history.start({pushState: true, root: "/mm+m/"});
