Material Design: [Pickers](https://www.google.com/design/spec/components/pickers.html#pickers-date-pickers)
An custom Polymer element created to provide a datepicker element that is more compelling and rich with features.
Example:
<app-datepicker><app-datepicker>
<app-datepicker-dialog></app-datepicker-dialog>
<app-datepicker-dialog modal></app-datepicker-dialog>
<app-datepicker-dialog with-backdrop></app-datepicker-dialog>
<app-datepicker view="horizontal"></app-datepicker>
<app-datepicker theme="dark-theme"></app-datepicker>
`app-datepicker` provides a regular datepicker element.
While `app-datepicker-dialog` has a `app-datepicker` being wrapped inside a dialog.
~~### ( Coming soon!) Generating your own boilerplate code of the element `app-datepicker` or `app-datepicker-dialog`~~
~~At the end of the demo, there is a section where user can play around with to generate your own boilerplate code with the attributes provided. Let's go and check out the demo!~~
### Styling
By default, the datepicker is in `light-theme` and now you are able to style almost all possible sections of the datepicker with your own choices of color.
**__ ** Note: As of release v2.4.0 the datepicker includes some basic themes that can be set via `theme` property: `dark-theme`, `light-theme`, or `goog-theme`.__*
Style the datepicker with CSS as you would a normal DOM element.
app-datepicker-dialog#darkThemedDialog {
background: #424242;
--app-datepicker-bg: #424242;
--app-datepicker-selection-bg: #555555;
--app-datepicker-selection-color: #cccccc;
--app-datepicker-iron-selected: #FFFFFF;
--app-datepicker-calendar-bg: #424242;
--app-datepicker-calendar-color: #ffffff;
--app-datepicker-weekdays-color: #c6c6c6;
--app-datepicker-selected-day-bg: #80CBC4;
--app-datepicker-selected-day-color: #555555;
--app-datepicker-selected-year-bg: #f5f5f5;
--app-datepicker-selected-year-color: #80CBC4;
--app-datepicker-today-color: #80CBC4;
--app-datepicker-disabled-color: #ffff00;
--app-datepicker-icon-button-color: #ffff00;
--app-datepicker-icon-button-ink-color: #ffff00;
--app-datepicker-button-color: #80CBC4;
--app-datepicker-button-ink-color: #bcbcbc;
}
The following custom properties and mixin are also available for styling:
