+Element providing material design circular spinner.
+
+##### Example
+
+    <paper-spinner active></paper-spinner>
+
+The default spinner cycles between blue, red, yellow and green. It can be customized so
+that it uses one color only.
+
+##### Example
+
+    <style shim-shadowdom>
+      paper-spinner.blue::shadow .circle {
+        border-color: #4285f4;
+      }
+    </style>
+
+    <paper-spinner class="blue" active></paper-spinner>
+
+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).
+
+##### Example
+  <paper-spinner alt="Loading contacts list" active></paper-spinner>
