 `paper-slider` allows user to select a value from a range of values by
 moving the slider thumb.  The interactive nature of the slider makes it a
 great choice for settings that reflect intensity levels, such as volume,
 brightness, or color saturation.
 
 Example:
 
-```html
-<paper-slider></paper-slider>
-```
+    <paper-slider></paper-slider>
 
-Use `min` and `max` to specify the slider range. Default is `0` to `100`. For example:
-```html
-<paper-slider min="10" max="200" value="110"></paper-slider>
-```
+Use `min` and `max` to specify the slider range.  Default is 0 to 100.
 
-### Styling slider

+
+    <paper-slider min="10" max="200" value="110"></paper-slider>
