| 11 `paper-radio-button` is a button that can be either checked or unchecked. | |
| 12 User can tap the radio button to check it. But it cannot be unchecked by | |
| 13 tapping once checked. | |
| 14 | |
| 15 Use `paper-radio-group` to group a set of radio buttons. When radio buttons | |
| 16 are inside a radio group, only one radio button in the group can be checked. | |
| 17 | |
| 18 Example: | |
| 19 | |
| 20 <paper-radio-button></paper-radio-button> | |
| 21 | |

| 25 | |

| 27 color: #4285f4; | |
| 28 } | |
| 29 | |
| 30 To change the radio checked color: | |
| 31 | |
| 32 paper-radio-button::shadow #onRadio { | |
| 33 background-color: #4285f4; | |
| 34 } | |
| 35 | |
| 36 paper-radio-button[checked]::shadow #offRadio { | |
| 37 border-color: #4285f4; | |
| 38 } | |
| 39 | |
