Example setting size to 32px x 32px: 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: To use a different built-in set of icons, import the specific `iron-icons/ -icons.html`, and specify the icon as ` : `. For example, to use a communication icon, you would use: 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`: See [iron-iconset](iron-iconset) and [iron-iconset-svg](iron-iconset-svg) for more information about how to create a custom iconset. See the [iron-icons demo](iron-icons?view=demo:demo/index.html) to see the icons available in the various iconsets. To load a subset of icons from one of the default `iron-icons` sets, you can use the [poly-icon](https://poly-icon.appspot.com/) tool. It allows you to select individual icons, and creates an iconset from them that you can use directly in your elements. ### Styling The following custom properties are available for styling: Custom property | Description | Default |-| `iron-icon` | Mixin applied to the icon | {} `iron-icon-width` | Width of the icon | `24px` `iron-icon-height` | Height of the icon | `24px` `iron-icon-fill-color` | Fill color of the svg icon | `currentcolor` `iron-icon-stroke-color` | Stroke color of the svg icon | none @group Iron Elements @element iron-icon @demo demo/index.html @hero hero.svg @homepage polymer.github.ioNote 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. meta.byKey(’info’); Pure imperative form would be like: document.createElement(’iron-meta’).byKey(’info’); Or, in a Polymer element, you can include a meta in your template: ... this.$.meta.byKey(’info’); @group Iron Elements @demo demo/index.html @hero hero.svg @element iron-meta` component provides simple ways to use [CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes), also known as flexbox. This component provides two different ways to use flexbox: 1. [Layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html). The layout class stylesheet provides a simple set of class-based flexbox rules, that let you specify layout properties directly in markup. You must include this file in every element that needs to use them. Sample use: ``` ``` ```html horizontal layout center alignment ``` 2. [Custom CSS mixins](https://github.com/PolymerElements/iron-flex-layout/blob/master/iron-flex-layout.html). The mixin stylesheet includes custom CSS mixins that can be applied inside a CSS rule using the `@apply` function. Please note that the old [/deep/ layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/classes) are deprecated, and should not be used. To continue using layout properties directly in markup, please switch to using the new `dom-module`-based [layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html). Please note that the new version does not use `/deep/`, and therefore requires you to import the `dom-modules` in every element that needs to use them. A complete [guide](https://elements.polymer-project.org/guides/flex-layout) to ` ` is available. @group Iron Elements @pseudoElement iron-flex-layout @demo demo/index.html... this.$.xhr.send({url: url, body: params});With `auto` set to `true`, the element performs a request whenever its `url`, `params` or `body` properties are changed. Automatically generated requests will be debounced in the case that multiple attributes are changed sequentially. Note: The `params` attribute must be double quoted JSON. You can trigger a request explicitly by calling `generateRequest` on the element. @demo demo/index.html @hero hero.svg* * * Alternatively, you can also inline your resources inside the app itself: * * * * {{localize(’hello’, ’name’, ’Batman’)}} * * * * * @demo demo/index.html * @polymerBehavior Polymer.AppLocalizeBehavior */ Polymer.AppLocalizeBehavior = { /** * Internal singleton cache.
