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 | `--paper-indigo-500` `--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 | `{}` @group Paper Elements @demo demo/index.html --> <dom-module id="paper-fab"> <style> :host { display: inline-block; position: relative; outline: none; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; cursor: pointer; box-sizing: border-box; min-width: 0; width: 56px; height: 56px; background: var(--paper-fab-background, --paper-indigo-500); color: var(--text-primary-color); border-radius: 50%; padding: 16px; z-index: 0; @apply(--paper-fab); } :host([mini]) { width: 40px; height: 40px; padding: 8px; @apply(--paper-fab-mini); } :host([disabled]) { color: var(--paper-fab-disabled-text, --paper-grey-500); background: var(--paper-fab-disabled-background, --paper-grey-300); @apply(--paper-fab-disabled); } paper-material { border-radius: inherit; } </style> <template> <paper-ripple></paper-ripple> <paper-material class="content fit flex layout vertical center-center" elevation="[[elevation]]" animated> <iron-icon id="icon" src="[[src]]" icon="[[icon]]"></iron-icon> </paper-material> </template> </dom-module> <script> Polymer({ is: 'paper-fab', behaviors: [ Polymer.PaperButtonBehavior ], properties: { /** * The URL of an image for the icon.
