 `iron-pages` is used to select one of its children to show. One use is to cycle through a list of
 children "pages".
 
 Example:
 
-```html
-<iron-pages selected="0">
-  <div>One</div>
-  <div>Two</div>
-  <div>Three</div>
-</iron-pages>
-
-<script>
-  document.addEventListener('click', function(e) {
-    var pages = document.querySelector('iron-pages');
-    pages.selectNext();
-  });
-</script>
-```
+    <iron-pages selected="0">
+      <div>One</div>
+      <div>Two</div>
+      <div>Three</div>
+    </iron-pages>
+
+    <script>
+      document.addEventListener('click', function(e) {
+        var pages = document.querySelector('iron-pages');
+        pages.selectNext();
+      });
+    </script>
