-The `core-layout` element is a helper for using

-[CSS3 Flexible Boxes](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes).

-A `core-layout` element enables a set of css selectors for easy flexbox styling.

-Example:

- <core-layout>

- <div>Left</div>

- <div core-flex>Main</div>

- <div>Right</div>

- </core-layout>

- Renders something like this:

- ---------------------------------

- |-------------------------------|

- ||Left| Main |Right||

- |-------------------------------|

- ---------------------------------

-__Note__: the `core-layout` element applies layout to itself if it has children or to

-its parent element, if it does not. This feature allows you to apply layout to an

-arbitrary parent.

-Elements can layout horizontally, such that their items stack

-left to right or vertically, such that their items stack top to bottom. The

-default is horizontal. Set `vertical` to true to layout the elements vertically.

-To make a particular child _flexible_, use the `core-flex` attribute.

-You can control flexibility from 1 to 3 by giving the attribute a

-corresponding value. For other values, apply the css manually.

-It's common in flexbox parlance to hear the terms _main axis_ and _cross axis_.

-For a horizontal layout the main axis is horizontal and the cross axis is vertical.

-These are exchanged for a vertical layout.

-To effect alignment in the main axis, use the `justify` attribute. The

-supported values are `start`, `center`, `end`, and `between`.

-To effect alignment in the cross axis, use the `align` attribute. The

-supported values are `start`, `center`, and `end`.

-Note, it's also possible to include the `core-layout.css` stylesheet separate

-from the `core-layout` element. Including the element automatically includes

-the stylesheet. To use the stylesheet independent of the element, css classes

-should be used of the following form: `core-h`, `core-v`, `core-flex`,

-`core-justify-start`, and `core-align-start`.

-The `core-layout` and css file also provide a few commonly needed layout

-behaviors. Apply the `core-fit` class to fit an element to its container. To

-ensure a container will contain an element inside it with the `core-fit` class

-give it the `core-relative` class.

-More examples:

- <core-layout vertical>

- <div>Header</div>

- <div core-flex>Body</div>

- <div>Footer</div>

- </core-layout>

- ----------

- ||------||

- ||Header||

- ||------||

- ||Body ||

- || ||

- ||------||

- ||Footer||

- ||------||

- ----------

-Justify:

- <core-layout justify="end">

- <div core-flex>Left</div>

- <div>Main</div>

- <div>Right</div>

- </core-layout>

- ---------------------------------

- |-------------------------------|

- || Left|Main|Right||

- |-------------------------------|

- ---------------------------------

-Align:

- <core-layout align="center">

- <div>Left</div>

- <div core-flex>Main</div>

- <div>Right</div>

- </core-layout>

- ---------------------------------

- |-------------------------------|

- || | | ||

- ||Left| Main |Right||

- || | | ||

- |-------------------------------|

- ---------------------------------

-To layout contents of a parent element, place a `core-layout` inside of it:

- <some-element>

- <core-layout></core-layout>

- <div>Left</div>

- <div core-flex>Main</div>

- <div>Right</div>

- <some-element>

- ---------------------------------

- |-------------------------------|

- ||Left| Main |Right||

- |-------------------------------|

- ---------------------------------

-You may also use the `core-layout` stylesheet directly:

- <link rel="stylesheet" href="../core-layout/core-layout.css">

- <div class="core-h core-justify-end">

- <div core-flex>Left</div>

- <div>Main</div>

- <div>Right</div>

- </div>

- ---------------------------------

- |-------------------------------|

- || Left|Main|Right||

-/**

- * @group Polymer Core Elements

- *

- * The `core-iconset-svg` element allows users to define their own icon sets

- * that contain svg icons. The svg icon elements should be children of the

- * `core-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:

- *

- * <core-iconset-svg id="my-svg-icons" iconSize="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>

- * </core-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

- * `core-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 core-iconset-svg

- * @extends core-meta

- * @homepage github.io

-/**

- * @group Polymer Core Elements

- *

- * The `core-iconset` element allows users to define their own icon sets.

- * The `src` property specifies the url of the icon image. Multiple icons may

- * be included in this image and they may be organized into rows.

- * The `icons` property is a space separated list of names corresponding to the

- * icons. The names must be ordered as the icons are ordered in the icon image.

- * Icons are expected to be square and are the size specified by the `iconSize`

- * property. The `width` property corresponds to the width of the icon image

- * and must be specified if icons are arranged into multiple rows in the image.

- *

- * All `core-iconset` elements are available for use by other `core-iconset`

- * elements via a database keyed by id. Typically, an element author that wants

- * to support a set of custom icons uses a `core-iconset` to retrieve

- * and use another, user-defined iconset.

- *

- * Example:

- *

- * <core-iconset id="my-icons" src="my-icons.png" width="96" iconSize="24"

- * icons="location place starta stopb bus car train walk">

- * </core-iconset>

- *

- * This will automatically register the icon set "my-icons" to the iconset

- * database. To use these icons from within another element, make a

- * `core-iconset` element and call the `byId` method to retrieve a

- * given iconset. To apply a particular icon to an element, use the

- * `applyIcon` method. For example:

- *

- * iconset.applyIcon(iconNode, 'car');

- *

- * Themed icon sets are also supported. The `core-iconset` can contain child

- * `property` elements that specify a theme with an offsetX and offsetY of the

- * theme within the icon resource. For example.

- *

- * <core-iconset id="my-icons" src="my-icons.png" width="96" iconSize="24"

- * icons="location place starta stopb bus car train walk">

- * <property theme="special" offsetX="256" offsetY="24"></property>

- * </core-iconset>

- *

- * Then a themed icon can be applied like this:

- *

- * iconset.applyIcon(iconNode, 'car', 'special');

- *

- * @element core-iconset

- * @extends core-meta

- * @homepage github.io

-`core-meta` provides a method of constructing a self-organizing database.

-It is useful to collate element meta-data for things like catalogs and for

-designer.

-Example, an element folder has a `metadata.html` file in it, that contains a

-`core-meta`, something like this:

- <core-meta id="my-element" label="My Element">

- <property name="color" value="blue"></property>

- </core-meta>

-An application can import as many of these files as it wants, and then use

-`core-meta` again to access the collected data.

- <script>

- var meta = document.createElement('core-meta');

- console.log(meta.list); // dump a list of all meta-data elements that have been created

- </script>

-Use `byId(id)` to retrive a specific core-meta.

- <script>

- var meta = document.createElement('core-meta');

- console.log(meta.byId('my-element'));

- </script>

-By default all meta-data are stored in a single databse. If your meta-data

-have different types and want them to be stored separately, use `type` to

-differentiate them.

-Example:

- <core-meta id="x-foo" type="xElt"></core-meta>

- <core-meta id="x-bar" type="xElt"></core-meta>

- <core-meta id="y-bar" type="yElt"></core-meta>

- <script>

- var meta = document.createElement('core-meta');

- meta.type = 'xElt';

- console.log(meta.list);

-The `core-icon` element displays an icon using CSS background image. By default an icon renders as 24px square.

-Example using src:

- <core-icon src="star.png"></core-icon>

-Example setting size to 32px x 32px:

- <core-icon src="big_star.png" size="32"></core-icon>

-Example using icon from default iconset:

- <core-icon icon="menu"></core-icon>

-Example using icon `cherry` from custom iconset `fruit`:

- <core-icon icon="fruit:cherry"></core-icon>

-See [core-iconset](#core-iconset) and [core-iconset-svg](#core-iconset-svg) for more information about

-`core-header-panel` contains a header section and a content panel section.

-__Important:__ The `core-header-panel` will not display if its parent does not have a height.

-Using [layout attributes](http://www.polymer-project.org/docs/polymer/layout-attrs.html), you can easily make the `core-header-panel` fill the screen

- <body fullbleed layout vertical>

- <core-header-panel flex>

- <core-toolbar>

- <div>Hello World!</div>

- </core-toolbar>

- </core-header-panel>

- </body>

-or, if you would prefer to do it in CSS, just give `html`, `body`, and `core-header-panel` a height of 100%:

- html, body {

- height: 100%;

- margin: 0;

- }

- core-header-panel {

- height: 100%;

- }

-Special

-support is provided for scrolling modes when one uses a core-toolbar or equivalent

-for the header section.

-Example:

- <core-header-panel>

- <core-toolbar>Header</core-toolbar>

- <div>Content goes here...</div>

- </core-header-panel>

-If you want to use other than `core-toolbar` for the header, add

-`core-header` class to that element.

-Example:

- <core-header-panel>

- <div class="core-header">Header</div>

- <div>Content goes here...</div>

- </core-header-panel>

-Use `mode` to control the header and scrolling behavior.

- * `standard`: The header is a step above the panel. The header will consume the

- * panel at the point of entry, preventing it from passing through to the

- * opposite side.

- *

- * `seamed`: The header is presented as seamed with the panel.

- *

- * `waterfall`: Similar to standard mode, but header is initially presented as

- * seamed with panel, but then separates to form the step.

- * `waterfall-tall`: The header is initially taller (`tall` class is added to

- * the header). As the user scrolls, the header separates (forming an edge)

- * while condensing (`tall` class is removed from the header).

- *

- * `scroll`: The header keeps its seam with the panel, and is pushed off screen.

- *

- * `cover`: The panel covers the whole `core-header-panel` including the

- * header. This allows user to style the panel in such a way that the panel is

- * @fileoverview

- * some functions for browser-side pretty printing of code contained in html.

- *

- * <p>

- * For a fairly comprehensive set of languages see the

- * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>

- * file that came with this source. At a minimum, the lexer should work on a

- * number of languages including C and friends, Java, Python, Bash, SQL, HTML,

- * XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk

- * and a subset of Perl, but, because of commenting conventions, doesn't work on

- * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.

- * <p>

- * Usage: <ol>

- * <li> include this source file in an html page via

- * {@code <script type="text/javascript" src="/path/to/prettify.js"><\/script>}

- * <li> define style rules. See the example page for examples.

- * <li> mark the {@code <pre>} and {@code <code>} tags in your source with

- * {@code class=prettyprint.}

- * You can also use the (html deprecated) {@code <xmp>} tag, but the pretty

- * printer needs to do more substantial DOM manipulations to support that, so

- * some css styles may not be preserved.

- * </ol>

- * That's it. I wanted to keep the API as simple as possible, so there's no

- * need to specify which language the code is in, but if you wish, you can add

- * another class to the {@code <pre>} or {@code <code>} element to specify the

- * language, as in {@code <pre class="prettyprint lang-java">}. Any class that

- * starts with "lang-" followed by a file extension, specifies the file type.

- * See the "lang-*.js" files in this directory for code that implements

- * per-language file handlers.

- * <p>

- * Change log:<br>

- * cbeust, 2006/08/22

- * <blockquote>

- * Java annotations (start with "@") are now captured as literals ("lit")

- * </blockquote>

- * @requires console

- * all characters in sourceCode[index_n-1:index_n].

- *

- * The stylePatterns is a list whose elements have the form

- * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].

- *

- * Style is a style constant like PR_PLAIN, or can be a string of the

- * form 'lang-FOO', where FOO is a language extension describing the

- * language of the portion of the token in $1 after pattern executes.

- * E.g., if style is 'lang-lisp', and group 1 contains the text

- * '(hello (world))', then that portion of the token will be passed to the

- * registered lisp handler for formatting.

- * The text before and after group 1 will be restyled using this decorator

- * so decorators should take care that this doesn't result in infinite

- * recursion. For example, the HTML lexer rule for SCRIPT elements looks

- * something like ['lang-js', /<[s]cript>(.+?)<\/script>/]. This may match

- * '<script>foo()<\/script>', which would cause the current decorator to

- * be called with '<script>' which would not match the same rule since

- * group 1 must not be empty, so it would be instead styled as PR_TAG by

- * the generic tag rule. The handler registered for the 'js' extension would

- * then be called with 'foo()', and finally, the current decorator would

- * be called with '<\/script>' which would not match the original rule and

- * so the generic tag rule would identify it as a tag.

- *

- * Pattern must only match prefixes, and if it matches a prefix, then that

- * match is considered a token with the same style.

- *

- * Context is applied to the last non-whitespace, non-comment token

- * recognized.

- *

- * Shortcut is an optional string of characters, any of which, if the first

- * character, gurantee that this pattern and only this pattern matches.

- *

- * @param {Array} shortcutStylePatterns patterns that always start with

-`<core-selector>` is used to manage a list of elements that can be selected.

-The attribute `selected` indicates which item element is being selected.

-The attribute `multi` indicates if multiple items can be selected at once.

-Tapping on the item element would fire `core-activate` event. Use

-`core-select` event to listen for selection changes.

-Example:

- <core-selector selected="0">

- <div>Item 1</div>

- <div>Item 2</div>

- <div>Item 3</div>

- </core-selector>

-`<core-selector>` is not styled. Use the `core-selected` CSS class to style the selected element.

- <style>

- .item.core-selected {

-The `<core-selection>` element is used to manage selection state. It has no

-visual appearance and is typically used in conjunction with another element.

-For example, [core-selector](#core-selector)

-use a `<core-selection>` to manage selection.

-To mark an item as selected, call the `select(item)` method on

-`<core-selection>`. The item itself is an argument to this method.

-The `<core-selection>`element manages selection state for any given set of

-items. When an item is selected, the `core-select` event is fired.

-The attribute `multi` indicates if multiple items can be selected at once.

-Example:

- <polymer-element name="selection-example">

- <template>

- <style>

- polyfill-next-selector { content: ':host > .selected'; }

- ::content > .selected {

- font-weight: bold;

- font-style: italic;

-Displays formatted source documentation scraped from input urls.

-Documentation can be encoded into html comments () or using JsDoc notation (/** ... */).

-When using JsDoc notation, remember that the left-margin includes an asterisk and a single space.

-This is important for markdown constructs that count spaces. Code blocks for example, must be

-five spaces from the first asterisk.

-## Markdown

-Markdown format is supported.

-### Links

-Arbitrary links can be encoded using [standard markdown format](http://daringfireball.net/projects/markdown/syntax).

-[GitHub Flavored Markdown](https://help.github.com/articles/github-flavored-markdown) is also supported.

-Links to other topics can be made with hash-links [core-doc-viewer](#core-doc-viewer).

-### Code

-Example

- Four space indents indicate code blocks.

- <code>blocks are syntax highlighted</code>

- <script>

- while(true) {

- javascript('is highlighted also');

- }

- </script>

-### Blockquote

- > Blockquote is supported for long text that needs to wrap with a common left side indent.

-### Lists

-1. enumerated

-1. lists

-Use - or + for bullet points:

-- bullet

-- lists

-### Tables

-| First Header | Second Header |

-| ------------- | ------------- |

-| Content Cell | Content Cell |

-### HTML

-Arbitrary HTML is also supported
