 The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
 
 Example using src:
 
     <iron-icon src="star.png"></iron-icon>
 
 Example setting size to 32px x 32px:
 
     <iron-icon class="big" src="big_star.png"></iron-icon>
 
-    <style>
+    <style is="custom-style">
       .big {
-        height: 32px;
-        width: 32px;
+        --iron-icon-height: 32px;
+        --iron-icon-width: 32px;
       }
     </style>
 
 The iron elements include several sets of icons.
 To use the default set of icons, import  `iron-icons.html` and use the `icon` attribute to specify an icon:
 
     &lt;!-- import default iconset and iron-icon --&gt;
     <link rel="import" href="/components/iron-icons/iron-icons.html">
 
     <iron-icon icon="menu"></iron-icon>
 
 To use a different built-in set of icons, import  `iron-icons/<iconset>-icons.html`, and
 specify the icon as `<iconset>:<icon>`. For example:
 
     &lt;!-- import communication iconset and iron-icon --&gt;
     <link rel="import" href="/components/iron-icons/communication-icons.html">
 
     <iron-icon icon="communication:email"></iron-icon>
 
 You can also create custom icon sets of bitmap or SVG icons.
 
 Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
 
     <iron-icon icon="fruit:cherry"></iron-icon>
 
 See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about
 how to create a custom iconset.
 
-See [iron-icons](http://www.polymer-project.org/components/iron-icons/demo.html) for the default set of icons.
