| 18 `paper-checkbox` is a button that can be either checked or unchecked. User | |
| 19 can tap the checkbox to check or uncheck it. Usually you use checkboxes | |
| 20 to allow user to select multiple options from a set. If you have a single | |
| 21 ON/OFF option, avoid using a single checkbox and use `paper-toggle-button` | |
| 22 instead. | |
| 23 | |
| 24 Example: | |
| 25 | |
| 26 <paper-checkbox>label</paper-checkbox> | |
| 27 | |
| 28 <paper-checkbox checked> label</paper-checkbox> | |
