   == Adding Polymer Elements to Our Application
   
   In the previous step, we downloaded elements to bower_components directory. Now we are going to import these elements in our application.
  
positive.code: 
  To make the toolbar look better, we make the application toolbar to have a shadow that is shown only for the hero detail view, but not for the heroes list view. For this purpose we bind the `raised` class of the [elementname]#app-toolbar# to [propertyname]#isInChildView# property and add a style rule which applies the shadow mixin from [elementname]#paper-styles# to the [elementname]#app-toolbar# when it has the `raised` class.
  
  == Wrap Up
  
  All the tutorial steps are complete. Now you can use all powers of Polymer elements in your Angular 2 applications and know how to do it.
  
negative.code: 
  After opening the application, click the first row in the heroes list. You should see the detail view like in the following screenshot:
