+Material design: [Cards](https://www.google.com/design/spec/components/cards.html)
+
+`paper-card` is a container with a drop shadow.
+
+Example:
+
+    <paper-card heading="Card Title">
+      <div class="card-content">Some content</div>
+      <div class="card-actions">
+        <paper-button>Some action</paper-button>
+      </div>
+    </paper-card>
+
+Example - top card image:
+
+    <paper-card heading="Card Title" image="/path/to/image.png">
+      ...
+    </paper-card>
+
