Contains accessibility and keyboard navigation specification of Telerik and Kendo web components.

Out of the box, the Telerik UI for Blazor TextArea provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.


The TextArea is compliant with the [Web Content Accessibility Guidelines (WCAG) 2.2 AAA](https://www.w3.org/TR/WCAG22/) standards and [Section 508](https://www.section508.gov/) requirements, follows the [Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/WAI/ARIA/apg/) best practices for implementing the [keyboard navigation](#keyboard-navigation) for its `component` role, provides options for managing its focus and is tested against the most popular screen readers.

## WAI-ARIA


This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-input-inner` | `role=textbox` or `nodeName=textarea` | Describes the role of the component. |
|  | `label for` or `aria-label` or `aria-labelledby` | The input requires an accessible name that will be assigned to it. |
|  | `aria-required=true` | The attribute is rendered only when the TextArea is in a `form` HTML element and announces the required state of the component. |
|  | `aria-describedby=.k-form-hint id/.k-form-error id` | Points to the hint for the input, or if the input is invalid, to the error message. This attribute should only be present when a hint is set or when the input is invalid. |
|  | `aria-multiline=true` | Announces the multi-line behavior of the TextArea. |
|  | `aria-invalid=true` | The attribute is rendered only when the TextArea is in a form and announces the valid state of the component. |
