 Material design: [Dialogs](https://www.google.com/design/spec/components/dialogs.html)
 
 `<paper-dialog>` is a dialog with Material Design styling and optional animations when it is
 opened or closed. It provides styles for a header, content area, and an action area for buttons.
 You can use the `<paper-dialog-scrollable>` element (in its own repository) if you need a scrolling
 content area. See `Polymer.PaperDialogBehavior` for specifics.
 
 For example, the following code implements a dialog with a header, scrolling content area and
 buttons.
 
-    <paper-dialog>
-      <h2>Header</h2>
-      <paper-dialog-scrollable>
-        Lorem ipsum...
-      </paper-dialog-scrollable>
-      <div class="buttons">
-        <paper-button dialog-dismiss>Cancel</paper-button>
-        <paper-button dialog-confirm>Accept</paper-button>
-      </div>
-    </paper-dialog>
+```html
+<paper-dialog>
+  <h2>Header</h2>
+  <paper-dialog-scrollable>
+    Lorem ipsum...
+  </paper-dialog-scrollable>
+  <div class="buttons">
+    <paper-button dialog-dismiss>Cancel</paper-button>
+    <paper-button dialog-confirm>Accept</paper-button>
+  </div>
+</paper-dialog>
+```
 
 ### Styling
 
 See the docs for `Polymer.PaperDialogBehavior` for the custom properties available for styling
 this element.
 
 ### Animations
 
 Set the `entry-animation` and/or `exit-animation` attributes to add an animation when the dialog
 is opened or closed. See the documentation in
 [PolymerElements/neon-animation](https://github.com/PolymerElements/neon-animation) for more info.
 
 For example:
 
-    <link rel="import" href="components/neon-animation/animations/scale-up-animation.html">
-    <link rel="import" href="components/neon-animation/animations/fade-out-animation.html">
+```html
+<link rel="import" href="components/neon-animation/animations/scale-up-animation.html">
+<link rel="import" href="components/neon-animation/animations/fade-out-animation.html">
 
-    <paper-dialog entry-animation="scale-up-animation"
-                  exit-animation="fade-out-animation">
-      <h2>Header</h2>
-      <div>Dialog body</div>
-    </paper-dialog>
+<paper-dialog entry-animation="scale-up-animation"
+              exit-animation="fade-out-animation">
+  <h2>Header</h2>
+  <div>Dialog body</div>
+</paper-dialog>
+```
