+iron-a11y-keys-behavior
+=======================
+
+`Polymer.IronA11yKeysBehavior` provides a normalized interface for processing
+keyboard commands that pertain to [WAI-ARIA best practices](http://www.w3.org/TR/wai-aria-practices/#kbd_general_binding).
+The element takes care of browser differences with respect to Keyboard events
+and uses an expressive syntax to filter key presses.
+
+Use the `keyBindings` prototype property to express what combination of keys
+will trigger the event to fire.
+
+Use the `key-event-target` attribute to set up event handlers on a specific
+node.
+The `keys-pressed` event will fire when one of the key combinations set with the
+`keys` property is pressed.

+iron-icon
+=========
+
+The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
+
+Example using src:
+
+```html
+<iron-icon src="star.png"></iron-icon>
+```
+
+Example setting size to 32px x 32px:
+
+```html
+<iron-icon class="big" src="big_star.png"></iron-icon>
+
+<style>
+  .big {
+    height: 32px;
+    width: 32px;
+  }
+</style>
+```
+
+The iron elements include several sets of icons.
+To use the default set of icons, import  `iron-icons.html` and use the `icon` attribute to specify an icon:
+
+```html
+<!-- import default iconset and iron-icon -->
+<link rel="import" href="/components/iron-icons/iron-icons.html">
+
+<iron-icon icon="menu"></iron-icon>
+```
+
+To use a different built-in set of icons, import  `iron-icons/<iconset>-icons.html`, and
+specify the icon as `<iconset>:<icon>`. For example:
+
+```html
+<!-- import communication iconset and iron-icon -->
+<link rel="import" href="/components/iron-icons/communication-icons.html">
+
+<iron-icon icon="communication:email"></iron-icon>
+```
+
+You can also create custom icon sets of bitmap or SVG icons.
+
+Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
+
+```html
+<iron-icon icon="fruit:cherry"></iron-icon>
+```
+
+See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about
+how to create a custom iconset.
+
+See [iron-icons](http://www.polymer-project.org/components/iron-icons/demo.html) for the default set of icons.

+
+The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
+
+Example using src:
+
+    <iron-icon src="star.png"></iron-icon>
+
+Example setting size to 32px x 32px:
+
+    <iron-icon class="big" src="big_star.png"></iron-icon>
+
+    <style is="custom-style">
+      .big {
+        --iron-icon-height: 32px;
+        --iron-icon-width: 32px;
+      }
+    </style>
+
+The iron elements include several sets of icons.
+To use the default set of icons, import  `iron-icons.html` and use the `icon` attribute to specify an icon:
+
+    &lt;!-- import default iconset and iron-icon --&gt;
+    <link rel="import" href="/components/iron-icons/iron-icons.html">
+
+    <iron-icon icon="menu"></iron-icon>
+
+To use a different built-in set of icons, import  `iron-icons/<iconset>-icons.html`, and
+specify the icon as `<iconset>:<icon>`. For example:
+
+    &lt;!-- import communication iconset and iron-icon --&gt;
+    <link rel="import" href="/components/iron-icons/communication-icons.html">
+
+    <iron-icon icon="communication:email"></iron-icon>
+
+You can also create custom icon sets of bitmap or SVG icons.
+
+Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
+
+    <iron-icon icon="fruit:cherry"></iron-icon>
+
+See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about
+how to create a custom iconset.
+
+See [iron-icons](https://elements.polymer-project.org/elements/iron-icons?view=demo:demo/index.html) for the default set of icons.
+
+
+### Styling
+
+The following custom properties are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--iron-icon-width` | Width of the icon | `24px`
+`--iron-icon-height` | Height of the icon | `24px`

+`iron-icons` is a utility import that includes the definition for the `iron-icon` element, `iron-iconset-svg` element, as well as an import for the default icon set.
+
+The `iron-icons` directory also includes imports for additional icon sets that can be loaded into your project.
+
+Example loading icon set:
+
+    <link rel="import" href="../iron-icons/maps-icons.html">
+
+To use an icon from one of these sets, first prefix your `iron-icon` with the icon set name, followed by a colon, ":", and then the icon id.
+
+Example using the directions-bus icon from the maps icon set:
+
+    <iron-icon icon="maps:directions-bus"></iron-icon>
+
+
+See [iron-icon](#iron-icon) for more information about working with icons.
+
+See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about how to create a custom iconset.

+  /**
+   * The `iron-iconset-svg` element allows users to define their own icon sets
+   * that contain svg icons. The svg icon elements should be children of the
+   * `iron-iconset-svg` element. Multiple icons should be given distinct id's.
+   *
+   * Using svg elements to create icons has a few advantages over traditional
+   * bitmap graphics like jpg or png. Icons that use svg are vector based so they
+   * are resolution independent and should look good on any device. They are
+   * stylable via css. Icons can be themed, colorized, and even animated.
+   *
+   * Example:
+   *
+   *     <iron-iconset-svg name="my-svg-icons" size="24">
+   *       <svg>
+   *         <defs>
+   *           <g id="shape">
+   *             <rect x="50" y="50" width="50" height="50" />
+   *             <circle cx="50" cy="50" r="50" />
+   *           </g>
+   *         </defs>
+   *       </svg>
+   *     </iron-iconset-svg>
+   *
+   * This will automatically register the icon set "my-svg-icons" to the iconset
+   * database.  To use these icons from within another element, make a
+   * `iron-iconset` element and call the `byId` method
+   * to retrieve a given iconset. To apply a particular icon inside an
+   * element use the `applyIcon` method. For example:
+   *
+   *     iconset.applyIcon(iconNode, 'car');
+   *
+   * @element iron-iconset-svg
+   * @demo demo/index.html

+iron-image
+==========
+
+`iron-image` is an element for displaying an image that provides useful sizing and
+preloading options not found on the standard `<img>` tag.
+
+The `sizing` option allows the image to be either cropped (`cover`) or
+letterboxed (`contain`) to fill a fixed user-size placed on the element.
+
+The `preload` option prevents the browser from rendering the image until the
+image is fully loaded.  In the interim, either the element's CSS `background-color`
+can be be used as the placeholder, or the `placeholder` property can be
+set to a URL (preferably a data-URI, for instant rendering) for an
+placeholder image.
+
+The `fade` option (only valid when `preload` is set) will cause the placeholder
+image/color to be faded out once the image is rendered.
+
+Examples:
+
+Basically identical to `<img src="...">` tag:
+
+```html
+<iron-image src="http://lorempixel.com/400/400"></iron-image>
+```
+
+Will letterbox the image to fit:
+
+```html
+<iron-image style="width:400px; height:400px;" sizing="contain"
+  src="http://lorempixel.com/600/400"></iron-image>
+```
+
+Will crop the image to fit:
+
+```html
+<iron-image style="width:400px; height:400px;" sizing="cover"
+  src="http://lorempixel.com/600/400"></iron-image>
+```
+
+Will show light-gray background until the image loads:
+
+```html
+<iron-image style="width:400px; height:400px; background-color: lightgray;"
+  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+```
+
+Will show a base-64 encoded placeholder image until the image loads:
+
+```html
+<iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
+  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+```
+
+Will fade the light-gray background out once the image is loaded:
+
+```html
+<iron-image style="width:400px; height:400px; background-color: lightgray;"
+  sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>

+<!--
+`iron-image` is an element for displaying an image that provides useful sizing and
+preloading options not found on the standard `<img>` tag.
+
+The `sizing` option allows the image to be either cropped (`cover`) or
+letterboxed (`contain`) to fill a fixed user-size placed on the element.
+
+The `preload` option prevents the browser from rendering the image until the
+image is fully loaded.  In the interim, either the element's CSS `background-color`
+can be be used as the placeholder, or the `placeholder` property can be
+set to a URL (preferably a data-URI, for instant rendering) for an
+placeholder image.
+
+The `fade` option (only valid when `preload` is set) will cause the placeholder
+image/color to be faded out once the image is rendered.
+
+Examples:
+
+  Basically identical to &lt;img src="..."&gt; tag:
+
+    <iron-image src="http://lorempixel.com/400/400"></iron-image>
+
+  Will letterbox the image to fit:
+
+    <iron-image style="width:400px; height:400px;" sizing="contain"
+      src="http://lorempixel.com/600/400"></iron-image>
+
+  Will crop the image to fit:
+
+    <iron-image style="width:400px; height:400px;" sizing="cover"
+      src="http://lorempixel.com/600/400"></iron-image>
+
+  Will show light-gray background until the image loads:
+
+    <iron-image style="width:400px; height:400px; background-color: lightgray;"
+      sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+
+  Will show a base-64 encoded placeholder image until the image loads:
+
+    <iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
+      sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+
+  Will fade the light-gray background out once the image is loaded:
+
+    <iron-image style="width:400px; height:400px; background-color: lightgray;"
+      sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>

+# iron-media-query
+
+`iron-media-query` can be used to data bind to a CSS media query.
+The `query` property is a bare CSS media query.
+The `query-matches` property is a boolean representing if the page matches that media query.

+Example:
+
+```html
+<iron-media-query query="(min-width: 600px)" query-matches="{{queryMatches}}"></iron-media-query>
+```

+iron-meta
+=========
+
+`iron-meta` is a generic element you can use for sharing information across the DOM tree.
+It uses [monostate pattern](http://c2.com/cgi/wiki?MonostatePattern) such that any
+instance of iron-meta has access to the shared
+information. You can use `iron-meta` to share whatever you want (or create an extension
+[like x-meta] for enhancements).
+
+The `iron-meta` instances containing your actual data can be loaded in an import,
+or constructed in any way you see fit. The only requirement is that you create them
+before you try to access them.
+
+Examples:
+
+If I create an instance like this:
+
+```html
+<iron-meta key="info" value="foo/bar"></iron-meta>
+```
+
+Note that value="foo/bar" is the metadata I've defined. I could define more
+attributes or use child nodes to define additional metadata.
+
+Now I can access that element (and it's metadata) from any iron-meta instance
+via the byKey method, e.g.
+
+```javascript
+meta.byKey('info').getAttribute('value');
+```
+
+Pure imperative form would be like:
+
+```javascript
+document.createElement('iron-meta').byKey('info').getAttribute('value');
+```
+
+Or, in a Polymer element, you can include a meta in your template:
+
+```html
+<iron-meta id="meta"></iron-meta>
+```
+
+```javascript
+this.$.meta.byKey('info').getAttribute('value');
+```

+iron-resizable-behavior
+=======================
+
+`IronResizableBehavior` is a behavior that can be used in Polymer elements to
+coordinate the flow of resize events between "resizers" (elements that control the
+size or hidden state of their children) and "resizables" (elements that need to be
+notified when they are resized or un-hidden by their parents in order to take
+action on their new measurements). 
+
+Elements that perform measurement should add the `IronResizableBehavior` behavior to
+their element definition and listen for the `iron-resize` event on themselves.
+This event will be fired when they become showing after having been hidden,
+when they are resized explicitly by another resizable, or when the window has been
+resized.
+
+Note, the `iron-resize` event is non-bubbling.

+iron-selector
+=============
+
+`iron-selector` is an element which can be used to manage a list of elements
+that can be selected.  Tapping on the item will make the item selected.  The `selected` indicates
+which item is being selected.  The default is to use the index of the item.
+
+Example:
+
+```html
+<iron-selector selected="0">
+  <div>Item 1</div>
+  <div>Item 2</div>
+  <div>Item 3</div>
+</iron-selector>
+```
+
+If you want to use the attribute value of an element for `selected` instead of the index,
+set `attrForSelected` to the name of the attribute.  For example, if you want to select item by
+`name`, set `attrForSelected` to `name`.
+
+Example:
+
+```html
+<iron-selector attr-for-selected="name" selected="foo">
+  <div name="foo">Foo</div>
+  <div name="bar">Bar</div>
+  <div name="zot">Zot</div>
+</iron-selector>
+```
+
+`iron-selector` is not styled. Use the `iron-selected` CSS class to style the selected element.
+
+Example:
+
+```html
+<style>
+  .iron-selected {
+    background: #eee;
+  }
+</style>
+
+...
+
+<iron-selector selected="0">
+  <div>Item 1</div>
+  <div>Item 2</div>
+  <div>Item 3</div>
+</iron-selector>
+```

+# paper-drawer-panel
+
+`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:
+
+```html
+<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:
+
+```html
+<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` 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>

+  paper-drawer-panel {
+    --paper-drawer-panel-main-container: {

+
+To change the drawer container when it's in the left side:
+  paper-drawer-panel {
+    --paper-drawer-panel-left-drawer-container: {
+      background-color: white;
+    };
+  }

+paper-fab
+=========
+
+Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Button</a>
+
+`paper-fab` is a floating action button. It contains an image placed in the center and
+comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When
+the user touches the button, a ripple effect emanates from the center of the button.
+
+You may import `iron-icons` to use with this element, or provide a URL to a custom icon.
+See `iron-iconset` for more information about how to use a custom icon set.
+
+Example:
+
+```html
+<link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+<paper-fab icon="add"></paper-fab>
+<paper-fab mini icon="favorite"></paper-fab>
+<paper-fab src="star.png"></paper-fab>
+```
+
+Styling
+-------
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, the icon will inherit the foreground color of the button.
+
+```html
+<!-- make a blue "cloud" button -->
+<paper-fab icon="cloud" style="color: blue;"></paper-fab>
+```
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using this selector:
+
+```css
+/* make #my-button use a blue ripple instead of foreground color */
+#my-button::shadow #ripple {
+  color: blue;
+}
+```
+
+The opacity of the ripple is not customizable via CSS.

+Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Button</a>
+
+`paper-fab` is a floating action button. It contains an image placed in the center and
+comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When
+the user touches the button, a ripple effect emanates from the center of the button.
+
+You may import `iron-icons` to use with this element, or provide a URL to a custom icon.
+See `iron-iconset` for more information about how to use a custom icon set.
+
+Example:
+
+    <link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+    <paper-fab icon="add"></paper-fab>
+    <paper-fab mini icon="favorite"></paper-fab>
+    <paper-fab src="star.png"></paper-fab>
+
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-fab-background` | The background color of the button | `--accent-color`
+`--paper-fab-keyboard-focus-background` | The background color of the button when focused | `--paper-pink-900`
+`--paper-fab-disabled-background` | The background color of the button when it's disabled | `--paper-grey-300`
+`--paper-fab-disabled-text` | The text color of the button when it's disabled | `--paper-grey-500`
+`--paper-fab` | Mixin applied to the button | `{}`
+`--paper-fab-mini` | Mixin applied to a mini button | `{}`
+`--paper-fab-disabled` | Mixin applied to a disabled button | `{}`

+paper-icon-button
+=================
+
+Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Buttons</a>
+
+`paper-icon-button` is a button with an image placed at the center. When the user touches
+the button, a ripple effect emanates from the center of the button.
+
+`paper-icon-button` includes a default icon set.  Use `icon` to specify which icon
+from the icon set to use.
+
+```html
+<paper-icon-button icon="menu"></paper-icon-button>
+```
+
+See [`iron-iconset`](#iron-iconset) for more information about
+how to use a custom icon set.
+
+Example:
+
+```html
+<link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+<paper-icon-button icon="favorite"></paper-icon-button>
+<paper-icon-button src="star.png"></paper-icon-button>
+```
+
+Styling
+-------
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, they will inherit the foreground color of the button.
+
+```html
+<!-- make a red "favorite" button -->
+<paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
+```
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using this selector:
+
+```css
+/* make #my-button use a blue ripple instead of foreground color */
+#my-button::shadow #ripple {
+  color: blue;
+}
+```
+
+The opacity of the ripple is not customizable via CSS.

+Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Buttons</a>
+
+`paper-icon-button` is a button with an image placed at the center. When the user touches
+the button, a ripple effect emanates from the center of the button.
+
+`paper-icon-button` includes a default icon set.  Use `icon` to specify which icon
+from the icon set to use.
+
+    <paper-icon-button icon="menu"></paper-icon-button>
+
+See [`iron-iconset`](#iron-iconset) for more information about
+how to use a custom icon set.
+
+Example:
+
+    <link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+    <paper-icon-button icon="favorite"></paper-icon-button>
+    <paper-icon-button src="star.png"></paper-icon-button>
+
+###Styling
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, they will inherit the foreground color of the button.
+
+    /* make a red "favorite" button */
+    <paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using this selector:
+
+    /* make #my-button use a blue ripple instead of foreground color */
+    #my-button::shadow #ripple {
+      color: blue;
+    }
+
+The opacity of the ripple is not customizable via CSS.
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-icon-button-disabled-text` | The color of the disabled button | `--primary-text-color`
+`--paper-icon-button-ink-color` | Selected/focus ripple color | `--default-primary-color`
+`--paper-icon-button` | Mixin for a button | `{}`
+`--paper-icon-button-disabled` | Mixin for a disabled button | `{}`

+`<paper-icon-item>` is a convenience element to make an item with icon. It is a non interactive list
+item with a fixed-width icon area, according to Material Design. This is useful if the icons are of
+varying widths, but you want the item bodies to line up. Use this like a `<paper-item>`. The child
+node with the attribute `item-icon` is placed in the icon area.

+Example:
+
+```html
+<paper-material elevation="1">

+`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+    <paper-menu>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
+and multiple item can be selected.
+
+    <paper-menu multi>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-menu-background-color`   | Menu background color                                            | `--primary-background-color`
+`-paper-menu-color`               | Menu foreground color                                            | `--primary-text-color`
+`--paper-menu-disabled-color`     | Foreground color for a disabled item                             | `--disabled-text-color`
+`--paper-menu`                    | Mixin applied to the menu                                        | `{}`
+`--paper-menu-selected-item`      | Mixin applied to the selected item                               | `{}`
+`--paper-menu-focused-item`       | Mixin applied to the focused item                                | `{}`
+`--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}`
+
+### Accessibility
+
+`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
+down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
+of a menu item will also focus it.

+paper-ripple
+============
+
+`paper-ripple` provides a visual effect that other paper elements can
+use to simulate a rippling effect emanating from the point of contact.  The
+effect can be visualized as a concentric circle with motion.
+
+Example:
+
+```html
+<paper-ripple></paper-ripple>
+```
+
+`paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple
+effect when touches on it.  You can also defeat the default behavior and
+manually route the down and up actions to the ripple element.  Note that it is
+important if you call downAction() you will have to make sure to call
+upAction() so that `paper-ripple` would end the animation loop.
+
+Example:
+
+```html
+<paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
+...
+<script>
+  downAction: function(e) {
+    this.$.ripple.downAction({x: e.x, y: e.y});
+  },
+  upAction: function(e) {
+    this.$.ripple.upAction();
+  }
+</script>
+```
+
+Styling ripple effect:
+
+Use CSS color property to style the ripple:
+
+```css
+paper-ripple {
+  color: #4285f4;
+}
+```
+
+Note that CSS color property is inherited so it is not required to set it on
+the `paper-ripple` element directly.
+
+
+By default, the ripple is centered on the point of contact. Apply the ``recenters`` attribute to have the ripple grow toward the center of its container.
+
+```html
+<paper-ripple recenters></paper-ripple>
+```
+
+Apply `center` to center the ripple inside its container from the start.
+
+```html
+<paper-ripple center></paper-ripple>
+```
+
+Apply `circle` class to make the rippling effect within a circle.
+
+```html
+<paper-ripple class="circle"></paper-ripple>
+```

+`paper-ripple` provides a visual effect that other paper elements can
+use to simulate a rippling effect emanating from the point of contact.  The
+effect can be visualized as a concentric circle with motion.
+
+Example:
+
+    <paper-ripple></paper-ripple>
+
+`paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple
+effect when touches on it.  You can also defeat the default behavior and
+manually route the down and up actions to the ripple element.  Note that it is
+important if you call downAction() you will have to make sure to call
+upAction() so that `paper-ripple` would end the animation loop.
+
+Example:
+
+    <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
+    ...
+    downAction: function(e) {
+      this.$.ripple.downAction({x: e.x, y: e.y});
+    },
+    upAction: function(e) {
+      this.$.ripple.upAction();
+    }
+
+Styling ripple effect:
+
+  Use CSS color property to style the ripple:
+
+    paper-ripple {
+      color: #4285f4;
+    }
+
+  Note that CSS color property is inherited so it is not required to set it on
+  the `paper-ripple` element directly.
+
+By default, the ripple is centered on the point of contact.  Apply the `recenters`
+attribute to have the ripple grow toward the center of its container.
+
+    <paper-ripple recenters></paper-ripple>
+
+You can also  center the ripple inside its container from the start.
+
+    <paper-ripple center></paper-ripple>
+
+Apply `circle` class to make the rippling effect within a circle.

+    <paper-ripple class="circle"></paper-ripple>

+paper-scroll-header-panel
+========================
+
+`paper-scroll-header-panel` contains a header section and a content section. The header is initially on the top part of the view but it scrolls away with the rest of the scrollable content. Upon scrolling slightly up at any point, the header scrolls back into view. This saves screen space and allows users to access important controls by easily moving them back to the view.
+
+Important: The `paper-scroll-header-panel` will not display if its parent does not have a height. Using layout classes, you can easily make the `paper-scroll-header-panel` fill the screen
+
+```html
+<body class="fullbleed layout vertical">
+  <paper-scroll-header-panel class="flex">
+    <paper-toolbar>
+      Hello World!
+    </paper-toolbar>
+  </paper-scroll-header-panel>
+</body>
+```
+or, if you would prefer to do it in CSS, just give html, body, and `paper-scroll-header-panel` a height of 100%:
+```css
+html, body {
+  height: 100%;
+  margin: 0;
+}
+paper-scroll-header-panel {
+  height: 100%;
+}
+```
+`paper-scroll-header-panel` works well with `paper-toolbar` but can use any element that represents a header by adding a `paper-header` class to it.
+
+```html
+<paper-scroll-header-panel>
+  <paper-toolbar>Header</paper-toolbar>
+  <div>Content goes here...</div>
+</paper-scroll-header-panel>
+```
+
+### Styling scroll-header-panel:
+
+To change background for toolbar when it is at its full size:
+
+```css
+paper-scroll-header-panel {
+  --paper-scroll-header-panel-full-header: {
+    background-color: red;
+  };
+}
+```
+
+To change the background for toolbar when it is condensed:
+
+```css
+paper-scroll-header-panel {
+  --paper-scroll-header-panel-condensed-header: {
+    background-color: #f4b400;
+  };
+}
+```

+`paper-scroll-header-panel` contains a header section and a content section.  The
+header is initially on the top part of the view but it scrolls away with the
+rest of the scrollable content.  Upon scrolling slightly up at any point, the
+header scrolls back into view.  This saves screen space and allows users to
+access important controls by easily moving them back to the view.
+
+__Important:__ The `paper-scroll-header-panel` will not display if its parent does not have a height.
+
+Using [layout classes](https://www.polymer-project.org/1.0/docs/migration.html#layout-attributes) or custom properties, you can easily make the `paper-scroll-header-panel` fill the screen
+
+    <body class="fullbleed layout vertical">
+      <paper-scroll-header-panel class="flex">
+        <paper-toolbar>
+          <div>Hello World!</div>
+        </paper-toolbar>
+      </paper-scroll-header-panel>
+    </body>
+
+or, if you would prefer to do it in CSS, just give `html`, `body`, and `paper-scroll-header-panel` a height of 100%:
+
+    html, body {
+      height: 100%;
+      margin: 0;
+    }
+    paper-scroll-header-panel {
+      height: 100%;
+    }
+
+`paper-scroll-header-panel` works well with `paper-toolbar` but can use any element
+that represents a header by adding a `paper-header` class to it.
+
+    <paper-scroll-header-panel>
+      <paper-toolbar>Header</paper-toolbar>
+      <div>Content goes here...</div>
+    </paper-scroll-header-panel>
+
+Styling scroll-header-panel:
+
+To change background for toolbar when it is at its full size:
+
+    paper-scroll-header-panel {
+      --paper-scroll-header-panel-full-header: {
+        background-color: red;
+      };
+    }
+
+To change the background for toolbar when it is condensed:
+
+    paper-scroll-header-panel {
+      --paper-scroll-header-panel-condensed-header: {
+        background-color: #f4b400;

+paper-toolbar
+============
+
+`paper-toolbar` is a horizontal bar containing items that can be used for
+label, navigation, search and actions.  The items place inside the
+`paper-toolbar` are projected into a `class="horizontal center layout"` container inside of
+`paper-toolbar`'s Shadow DOM.  You can use flex attributes to control the items'
+sizing.
+
+Example:
+
+```html
+<paper-toolbar>
+  <paper-icon-button icon="menu" on-tap="{{menuAction}}"></paper-icon-button>
+  <div class="title">Title</div>
+  <paper-icon-button icon="more" on-tap="{{moreAction}}"></paper-icon-button>
+</paper-toolbar>
+```
+
+`paper-toolbar` has a standard height, but can made be taller by setting `tall`
+class on the `paper-toolbar`.  This will make the toolbar 3x the normal height.
+
+```html
+<paper-toolbar class="tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+</paper-toolbar>
+```
+
+Apply `medium-tall` class to make the toolbar medium tall.  This will make the
+toolbar 2x the normal height.
+
+```html
+<paper-toolbar class="medium-tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+</paper-toolbar>
+```
+
+When `tall`, items can pin to either the top (default), middle or bottom.  Use
+`middle` class for middle content and `bottom` class for bottom content.
+
+```html
+<paper-toolbar class="tall">
+  <paper-icon-button icon="menu"></paper-icon-button>
+  <div class="title middle">Middle Title</div>
+  <div class="title bottom">Bottom Title</div>
+</paper-toolbar>
+```
+
+For `medium-tall` toolbar, the middle and bottom contents overlap and are
+pinned to the bottom.  But `middleJustify` and `bottomJustify` attributes are
+still honored separately.

+`--paper-toolbar-color`      | Toolbar foreground color     | `--text-primary-color`
+`--paper-toolbar`            | Mixin applied to the toolbar | `{}`
+

+webcomponents.js
+================
+
+[![Join the chat at https://gitter.im/webcomponents/webcomponentsjs](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/webcomponents/webcomponentsjs?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+A suite of polyfills supporting the [Web Components](http://webcomponents.org) specs:
+
+**Custom Elements**: allows authors to define their own custom tags ([spec](https://w3c.github.io/webcomponents/spec/custom/)).
+
+**HTML Imports**: a way to include and reuse HTML documents via other HTML documents ([spec](https://w3c.github.io/webcomponents/spec/imports/)).
+
+**Shadow DOM**: provides encapsulation by hiding DOM subtrees under shadow roots ([spec](https://w3c.github.io/webcomponents/spec/shadow/)).
+
+This also folds in polyfills for `MutationObserver` and `WeakMap`.
+
+
+## Releases
+
+Pre-built (concatenated & minified) versions of the polyfills are maintained in the [tagged versions](https://github.com/webcomponents/webcomponentsjs/releases) of this repo. There are two variants:
+
+`webcomponents.js` includes all of the polyfills.
+
+`webcomponents-lite.js` includes all polyfills except for shadow DOM.
+
+
+## Browser Support
+
+Our polyfills are intended to work in the latest versions of evergreen browsers. See below
+for our complete browser support matrix:
+
+| Polyfill   | IE10 | IE11+ | Chrome* | Firefox* | Safari 7+* | Chrome Android* | Mobile Safari* |
+| ---------- |:----:|:-----:|:-------:|:--------:|:----------:|:---------------:|:--------------:|
+| Custom Elements | ~ | ✓ | ✓ | ✓ | ✓ | ✓| ✓ |
+| HTML Imports | ~ | ✓ | ✓ | ✓ | ✓| ✓| ✓ |
+| Shadow DOM | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
+| Templates | ✓ | ✓ | ✓ | ✓| ✓ | ✓ | ✓ |
+
+
+*Indicates the current version of the browser
+
+~Indicates support may be flaky. If using Custom Elements or HTML Imports with Shadow DOM,
+you will get the non-flaky Mutation Observer polyfill that Shadow DOM includes.
+
+The polyfills may work in older browsers, however require additional polyfills (such as classList)
+to be used. We cannot guarantee support for browsers outside of our compatibility matrix.
+
+
+### Manually Building
+
+If you wish to build the polyfills yourself, you'll need `node` and `gulp` on your system:
+
+ * install [node.js](http://nodejs.org/) using the instructions on their website
+ * use `npm` to install [gulp.js](http://gulpjs.com/): `npm install -g gulp`
+
+Now you are ready to build the polyfills with:
+
+    # install dependencies
+    npm install
+    # build
+    gulp build
+
+The builds will be placed into the `dist/` directory.

+
+## Helper utilities
+
+### `WebComponentsReady`
+
+Under native HTML Imports, `<script>` tags in the main document block the loading of such imports. This is to ensure the imports have loaded and any registered elements in them have been upgraded. 
+
+The webcomponents.js and webcomponents-lite.js polyfills parse element definitions and handle their upgrade asynchronously. If prematurely fetching the element from the DOM before it has an opportunity to upgrade, you'll be working with an `HTMLUnknownElement`. 
+
+For these situations (or when you need an approximate replacement for the Polymer 0.5 `polymer-ready` behavior), you can use the `WebComponentsReady` event as a signal before interacting with the element. The criteria for this event to fire is all Custom Elements with definitions registered by the time HTML Imports available at load time have loaded have upgraded.
+
+```js
+window.addEventListener('WebComponentsReady', function(e) {
+  // imports are loaded and elements have been registered
+  console.log('Components are ready');
+});
+```
+
+## Known Issues
+
+  * [Custom element's constructor property is unreliable](#constructor)
+  * [Contenteditable elements do not trigger MutationObserver](#contentedit)
+  * [ShadowCSS: :host-context(...):host(...) doesn't work](#hostcontext)
+  * [execCommand isn't supported under Shadow DOM](#execcommand)
+
+### Custom element's constructor property is unreliable <a id="constructor"></a>
+See [#215](https://github.com/webcomponents/webcomponentsjs/issues/215) for background.
+
+In Safari and IE, instances of Custom Elements have a `constructor` property of `HTMLUnknownElementConstructor` and `HTMLUnknownElement`, respectively. It's unsafe to rely on this property for checking element types.
+
+It's worth noting that `customElement.__proto__.__proto__.constructor` is `HTMLElementPrototype` and that the prototype chain isn't modified by the polyfills(onto `ElementPrototype`, etc.)
+
+### Contenteditable elements do not trigger MutationObserver <a id="contentedit"></a>
+Using the MutationObserver polyfill, it isn't possible to monitor mutations of an element marked `contenteditable`.
+See [the mailing list](https://groups.google.com/forum/#!msg/polymer-dev/LHdtRVXXVsA/v1sGoiTYWUkJ)
+
+### ShadowCSS: :host-context(...):host(...) doesn't work <a id="hostcontext"></a>
+See [#16](https://github.com/webcomponents/webcomponentsjs/issues/16) for background.
+
+Under the shadow DOM polyfill, rules like:
+```
+:host-context(.foo):host(.bar) {...}
+```
+don't work, despite working under native Shadow DOM. The solution is to use `polyfill-next-selector` like:
+
+```
+polyfill-next-selector { content: '.foo :host.bar, :host.foo.bar'; }
+```
+
+### execCommand and contenteditable isn't supported under Shadow DOM <a id="execcommand"></a>
+See [#212](https://github.com/webcomponents/webcomponentsjs/issues/212)
+
+`execCommand`, and `contenteditable` aren't supported under the ShadowDOM polyfill, with commands that insert or remove nodes being especially prone to failure.
