The Kendo UI for Angular DatePicker component is [WCAG 2.1 AAA](https://www.w3.org/TR/WCAG21/) and [Section 508](http://www.section508.gov/) compliant. The component also follows the [WAI-ARIA best practices](https://www.w3.org/WAI/ARIA/apg/) for implementing the keyboard navigation for its component role, and is tested against the popular screen readers.

## Wai-Aria

### DatePicker wrapper

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| .k-input-inner | `role=combobox` | The input element should follow the `combobox` specification. |
|  | `label for=` or `aria-label` or `aria-labelledby` | The input needs an accessible name to be assigned to it. |
|  | `aria-haspopup=grid` | Indicates the component has a Calendar Popup that implements `role="grid"`. |
|  | `aria-expanded=true/false` | Announces whether the Popup is visible or not. |
|  | `aria-controls=.k-animation-container id` | Points to the popup element. Signifies that the `combobox` element controls the Calendar `grid`. |
|  | `aria-activedescendent=.k-calendar-td id` | Points to the focused item (date/month/year) in the Calendar Popup. Should only be present when the Popup is open. |
|  | `disabled` or `aria-disabled` | Attribute is rendered only when the DatePicker is disabled. |
|  | `readonly` or `aria-readonly` | Attribute is rendered only when the DatePicker is readonly. |
|  | `aria-invalid=true` | Attribute is rendered only when the combobox is in form and announces the valid state of the component. |
|  | `tabindex=0` | The element must be focusable. |
| .k-input-button | `role=button` or `nodeName=button` | The element should either be a `<button>` element or should have `role="button"` assigned. |
|  | `aria-label` | The button needs an accessible name to be assigned to it. |
|  | `tabindex=-1` | Button element should not be focusable. |
