  +Now that everything is set, we can add any Polymer elements to our application using their element names in templates,
  +and the [classname]#PolymerElement# directive in code.
   For example, modify the [filename]#src/app/app.component.html# to have the following code:
   
   [source,html]
  
positive.code: 
  [source]
  ----
  public/bower_components

  Next we will modify the application index HTML file to load the web components polyfill and import the Polymer elements. Open the [filename]#src/index.html# file and append the following lines to the [elementname]#head# section:
  
  [source,html]
  .src/index.html head additions
  
negative.code: [prompt]#$# [command]#ng# serve
