@polymer/iron-flex-layout
Advanced tools
The <iron-flex-layout>
component provides simple ways to use
CSS flexible box layout,
also known as flexbox. Note that this is an old element, that was written
before all modern browsers had non-prefixed flex styles. As such, nowadays you
don't really need to use this element anymore, and can use CSS flex styles
directly in your code.
See: Documentation, Demo.
This component provides two different ways to use flexbox:
Layout classes. 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.
Custom CSS mixins.
The mixin stylesheet includes custom CSS mixins that can be applied inside a CSS rule using the @apply
function.
npm install --save @polymer/iron-flex-layout
import {PolymerElement, html} from '@polymer/polymer';
import '@polymer/iron-flex-layout/iron-flex-layout-classes.js';
class SampleElement extends PolymerElement {
static get template() {
return html`
<style is="custom-style" include="iron-flex iron-flex-alignment"></style>
<style>
.test { width: 100px; }
</style>
<div class="layout horizontal center-center">
<div class="test">horizontal layout center alignment</div>
</div>
`;
}
}
customElements.define('sample-element', SampleElement);
