 Material design: [Progress & activity](https://www.google.com/design/spec/components/progress-activity.html)
 
 Element providing a multiple color material design circular spinner.
 
-    <paper-spinner active></paper-spinner>
+```html
+<paper-spinner active></paper-spinner>
+```
 
 The default spinner cycles between four layers of colors; by default they are
 blue, red, yellow and green. It can be customized to cycle between four different
 colors. Use <paper-spinner-lite> for single color spinners.
 
 ### Accessibility
 
 Alt attribute should be set to provide adequate context for accessibility. If not provided,
 it defaults to 'loading'.
 Empty alt can be provided to mark the element as decorative if alternative content is provided
 in another form (e.g. a text block following the spinner).
 
-    <paper-spinner alt="Loading contacts list" active></paper-spinner>
+```html
+<paper-spinner alt="Loading contacts list" active></paper-spinner>
+```
