|
| +Material design: [Checkbox](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox)
|
| +
|
| +`paper-checkbox` is a button that can be either checked or unchecked. User
|
| +can tap the checkbox to check or uncheck it. Usually you use checkboxes
|
| +to allow user to select multiple options from a set. If you have a single
|
| +ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
|
| +instead.
|
| +
|
| +Example:
|
| +
|
| + <paper-checkbox>label</paper-checkbox>
|
| +
|
| + <paper-checkbox checked> label</paper-checkbox>
|
| +
|
| +### Styling
|
| +
|
| +The following custom properties and mixins are available for styling:
|
| +

| +`--paper-checkbox-unchecked-color` | Checkbox border color when the input is not checked | `--primary-text-color`
|
| +`--paper-checkbox-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color`
|
| +`--paper-checkbox-checked-color` | Checkbox color when the input is checked | `--primary-color`
|
| +`--paper-checkbox-checked-ink-color` | Selected/focus ripple color when the input is checked | `--primary-color`
|
| +`--paper-checkbox-checkmark-color` | Checkmark color | `white`
|
| +`--paper-checkbox-label-color` | Label color | `--primary-text-color`
|
| +`--paper-checkbox-label-checked-color` | Label color when the input is checked | `--paper-checkbox-label-color`
|
| +`--paper-checkbox-label-spacing` | Spacing between the label and the checkbox | `8px`
|
| +`--paper-checkbox-label` | Mixin applied to the label | `{}`
|
| +`--paper-checkbox-label-checked` | Mixin applied to the label when the input is checked | `{}`
|
| +`--paper-checkbox-error-color` | Checkbox color when invalid | `--error-color`
|
| +`--paper-checkbox-size` | Size of the checkbox | `18px`
|
| +`--paper-checkbox-ink-size` | Size of the ripple | `48px`
|
| +`--paper-checkbox-margin` | Margin around the checkbox container | `initial`
|
| +`--paper-checkbox-vertical-align` | Vertical alignment of the checkbox container | `middle`
|
| +
|
| +This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
|
| +In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.
