##<paper-checkbox>
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:
```html
label
label
```
