+The `core-range` element is used for managing a numeric value within a given 
+range.  It has no visual appearance and is typically used in conjunction with 
+another element.
+
+One can build a progress bar using `core-range` like this:
+
+    <core-range min="0" max="200" value="100" ratio="{{ratio}}"></core-range>
+    <div class="progress-bar" style="width: {{ratio}}%;"></div>
