+
+
+Material design: [Navigation drawer](https://www.google.com/design/spec/patterns/navigation-drawer.html)
+
+`paper-drawer-panel` contains a drawer panel and a main panel.  The drawer
+and the main panel are side-by-side with drawer on the left.  When the browser
+window size is smaller than the `responsiveWidth`, `paper-drawer-panel`
+changes to narrow layout.  In narrow layout, the drawer will be stacked on top
+of the main panel.  The drawer will slide in/out to hide/reveal the main
+panel.
+
+Use the attribute `drawer` to indicate that the element is the drawer panel and
+`main` to indicate that the element is the main panel.
+
+Example:
+
+    <paper-drawer-panel>
+      <div drawer> Drawer panel... </div>
+      <div main> Main panel... </div>
+    </paper-drawer-panel>
+
+The drawer and the main panels are not scrollable.  You can set CSS overflow
+property on the elements to make them scrollable or use `paper-header-panel`.
+
+Example:
+
+    <paper-drawer-panel>
+      <paper-header-panel drawer>
+        <paper-toolbar></paper-toolbar>
+        <div> Drawer content... </div>
+      </paper-header-panel>
+      <paper-header-panel main>
+        <paper-toolbar></paper-toolbar>
+        <div> Main content... </div>
+      </paper-header-panel>
+    </paper-drawer-panel>
+
+An element that should toggle the drawer will automatically do so if it's
+given the `paper-drawer-toggle` attribute.  Also this element will automatically
+be hidden in wide layout.
+
+Example:
+
+    <paper-drawer-panel>
+      <paper-header-panel drawer>
+        <paper-toolbar>
+          <div>Application</div>
+        </paper-toolbar>
+        <div> Drawer content... </div>
+      </paper-header-panel>
+      <paper-header-panel main>
+        <paper-toolbar>
+          <paper-icon-button icon="menu" paper-drawer-toggle></paper-icon-button>
+          <div>Title</div>
+        </paper-toolbar>
+        <div> Main content... </div>
+      </paper-header-panel>
+    </paper-drawer-panel>
+
+To position the drawer to the right, add `right-drawer` attribute.
+
+    <paper-drawer-panel right-drawer>
+      <div drawer> Drawer panel... </div>
+      <div main> Main panel... </div>
+    </paper-drawer-panel>
+
+### Styling
+
+To change the main container:
+
+    paper-drawer-panel {
+      --paper-drawer-panel-main-container: {
+        background-color: gray;
+      };
+    }
+
+To change the drawer container when it's in the left side:
+
+    paper-drawer-panel {
+      --paper-drawer-panel-left-drawer-container: {
+        background-color: white;
+      };
+    }
+
+To change the drawer container when it's in the right side:
+
+    paper-drawer-panel {
+      --paper-drawer-panel-right-drawer-container: {
+        background-color: white;
+      };
+    }
+
+To customize the scrim:
+
+    paper-drawer-panel {
+      --paper-drawer-panel-scrim: {
+        background-color: red;
+      };
+    }
+
+The following custom properties and mixins are available for styling:
