`paper-radio-button` is a button that can be either checked or unchecked.
|
|
User can tap the radio button to check it. But it cannot be unchecked by
|
|
tapping once checked.
|
|
|
|
Use `paper-radio-group` to group a set of radio buttons. When radio buttons
|
|
are inside a radio group, only one radio button in the group can be checked.
|
|
|
|
Example:
|
|
|
|
<paper-radio-button></paper-radio-button>
|
|
|
|
Styling radio button:
|
|
|
|
To change the ink color for checked state:
|
|
|
|
paper-radio-button::shadow #ink[checked] {
|
|
color: #4285f4;
|
|
}
|
|
|
|
To change the radio checked color:
|
|
|
|
paper-radio-button::shadow #onRadio {
|
|
background-color: #4285f4;
|
|
}
|
|
|
|
To change the ink color for unchecked state:
|
|
|
|
paper-radio-button::shadow #ink {
|
|
color: #b5b5b5;
|
|
}
|
|
|
|
To change the radio unchecked color:
|
|
|
|
paper-radio-button::shadow #offRadio {
|
|
border-color: #b5b5b5;
|
|
}
|
|
