 paper-toolbar
 ============
 
 `paper-toolbar` is a horizontal bar containing items that can be used for
 label, navigation, search and actions.  The items place inside the
 `paper-toolbar` are projected into a `class="horizontal center layout"` container inside of
 `paper-toolbar`'s Shadow DOM.  You can use flex attributes to control the items'
 sizing.
 
 Example:
 
 ```html
 <paper-toolbar>
   <paper-icon-button icon="menu" on-tap="{{menuAction}}"></paper-icon-button>
-  <div title>Title</div>
+  <div class="title">Title</div>
   <paper-icon-button icon="more" on-tap="{{moreAction}}"></paper-icon-button>
 </paper-toolbar>
 ```
 
 `paper-toolbar` has a standard height, but can made be taller by setting `tall`
 class on the `paper-toolbar`.  This will make the toolbar 3x the normal height.
 
 ```html
 <paper-toolbar class="tall">
   <paper-icon-button icon="menu"></paper-icon-button>
 </paper-toolbar>
 ```
 
 Apply `medium-tall` class to make the toolbar medium tall.  This will make the
 toolbar 2x the normal height.
 
 ```html
 <paper-toolbar class="medium-tall">
   <paper-icon-button icon="menu"></paper-icon-button>
 </paper-toolbar>
 ```
 
 When `tall`, items can pin to either the top (default), middle or bottom.  Use
 `middle` class for middle content and `bottom` class for bottom content.
 
 ```html
 <paper-toolbar class="tall">
   <paper-icon-button icon="menu"></paper-icon-button>
-  <div title class="middle">Middle Title</div>
-  <div title class="bottom">Bottom Title</div>
+  <div class="title middle">Middle Title</div>
+  <div class="title bottom">Bottom Title</div>
 </paper-toolbar>
 ```
 
 For `medium-tall` toolbar, the middle and bottom contents overlap and are
 pinned to the bottom.  But `middleJustify` and `bottomJustify` attributes are
 still honored separately.
