| 11 `paper-checkbox` is a button that can be either checked or unchecked. User | |
| 12 can tap the checkbox to check or uncheck it. Usually you use checkboxes | |
| 13 to allow user to select multiple options from a set. If you have a single | |
| 14 ON/OFF option, avoid using a single checkbox and use `paper-toggle-button` | |
| 15 instead. | |
| 16 | |
| 17 Example: | |
| 18 | |
| 19 <paper-checkbox></paper-checkbox> | |
| 20 | |
| 21 <paper-checkbox checked></paper-checkbox> | |
