Blazor TextBox Accessibility
Out of the box, the Telerik UI for Blazor TextBox provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The TextBox is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards](https://www.w3.org/TR/WCAG22/) and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the 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.
No role attribute is implemented as the html input type="text" element is sufficient for definining the purpose of the component.

role=textbox or nodeName=input
