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

| * 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 |

| * 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 |

| `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 |
| how to use a custom iconset. |
| |
| See [core-icons](#core-icons) for the default set of icons. To use the default set of icons you'll need to include an import for `core-icons.html`. |

| `core-toolbar` is a horizontal bar containing elements that can be used for |
| label, navigation, search and actions. |
| |
| <core-toolbar> |
| <core-icon-button icon="menu" on-tap="{{menuAction}}"></core-icon-button> |
| <div flex>Title</div> |
| <core-icon-button icon="more" on-tap="{{moreAction}}"></core-icon-button> |
| </core-toolbar> |
| |
| `core-toolbar` has a standard height, but can made be taller by setting `tall` |
| class on the `core-toolbar`. This will make the toolbar 3x the normal height. |
| |
| <core-toolbar class="tall"> |
| <core-icon-button icon="menu"></core-icon-button> |
| </core-toolbar> |
| |
| Apply `medium-tall` class to make the toolbar medium tall. This will make the |
| toolbar 2x the normal height. |
| |
| <core-toolbar class="medium-tall"> |
| <core-icon-button icon="menu"></core-icon-button> |
| </core-toolbar> |
| |
| When taller, elements can pin to either the top (default), middle or bottom. |
| |
| <core-toolbar class="tall"> |
| <core-icon-button icon="menu"></core-icon-button> |
| <div class="middle indent">Middle Title</div> |
| <div class="bottom indent">Bottom Title</div> |
| </core-toolbar> |
| |
| To make an element completely fit at the bottom of the toolbar, use `fit` along |
| with `bottom`. |
| |
| <core-toolbar class="tall"> |
| <div id="progressBar" class="bottom fit"></div> |

| <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. |

| * Controls header and scrolling behavior. Options are |
| * `standard`, `seamed`, `waterfall`, `waterfall-tall`, |
| * `waterfall-medium-tall`, `scroll` and `cover`. |
| * Default is `standard`. |
| * |
| * `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 |
| * partially covering the header. |

| * <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. |

| * '(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. |

| `<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 { |
| background: #eee; |
| } |
| </style> |
| ... |
| <core-selector> |
| <div class="item">Item 1</div> |

| 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'; } |

| |
| 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. |
