| Material design: [Buttons](https://www.google.com/design/spec/components/buttons.html) |
| |
| `paper-button` is a button. When the user touches the button, a ripple effect emanates |
| from the point of contact. It may be flat or raised. A raised button is styled with a |
| shadow. |
| |
| Example: |
| |
| <paper-button>Flat button</paper-button> |
| <paper-button raised>Raised button</paper-button> |
| <paper-button noink>No ripple effect</paper-button> |
| <paper-button toggles>Toggle-able button</paper-button> |
| |
| A button that has `toggles` true will remain `active` after being clicked (and |
| will have an `active` attribute set). For more information, see the `Polymer.IronButtonState` |
| behavior. |
| |
| You may use custom DOM in the button body to create a variety of buttons. For example, to |
| create a button with an icon and some text: |
| |
| <paper-button> |
| <iron-icon icon="favorite"></iron-icon> |
| custom button content |
| </paper-button> |
| |
| To use `paper-button` as a link, wrap it in an anchor tag. Since `paper-button` will already |
| receive focus, you may want to prevent the anchor tag from receiving focus as well by setting |
| its tabindex to -1. |
| |
| <a href="https://www.polymer-project.org/" tabindex="-1"> |
| <paper-button raised>Polymer Project</paper-button> |
| </a> |
| |
| ### Styling |
| |
| Style the button with CSS as you would a normal DOM element. |
| |
| paper-button.fancy { |
| background: green; |
| color: yellow; |
| } |
| |
| paper-button.fancy:hover { |
| background: lime; |
| } |
| |
| paper-button[disabled], |
| paper-button[toggles][active] { |
| background: red; |
| } |
| |
| By default, the ripple is the same color as the foreground at 25% opacity. You may |
| customize the color using the `--paper-button-ink-color` custom property. |
| |
| The following custom properties and mixins are also available for styling: |
| |
| Custom property | Description | Default |
| ----------------|-------------|---------- |
| `--paper-button-ink-color` | Background color of the ripple | `Based on the button's color` |
| `--paper-button` | Mixin applied to the button | `{}` |
| `--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}` |
| `--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}` |
| `--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}` |
