Material design: [Progress & activity](https://www.google.com/design/spec/components/progress-activity.html)
|
|
|
|
Element providing a multiple color material design circular spinner.
|
|
|
|
<paper-spinner active></paper-spinner>
|
|
|
|
The default spinner cycles between four layers of colors; by default they are
|
|
blue, red, yellow and green. It can be customized to cycle between four different
|
|
colors. Use <paper-spinner-lite> for single color spinners.
|
|
|
|
### Accessibility
|
|
|
|
Alt attribute should be set to provide adequate context for accessibility. If not provided,
|
|
it defaults to 'loading'.
|
|
Empty alt can be provided to mark the element as decorative if alternative content is provided
|
|
in another form (e.g. a text block following the spinner).
|
|
|
|
<paper-spinner alt="Loading contacts list" active></paper-spinner>
|
|
|
|
