Editor Accessibility
Out of the box, the Telerik UI for ASP.NET Core Editor provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The Editor is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards 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.
The Editor component has two distinctive modes - one with <textarea> and an <iframe> containing an HTML document and another one with only a contenteditable <div> (Inline Editor). The inline mode of the Editor does not require any particular ARIA attributes to be present in the widget.
Editor with textarea
| Selector | Attribute | Usage |
|---|---|---|
.k-iframe | tabindex=0 | The element must be part of the page tabsequence. |
label for or aria-label or aria-labelledby | The component focusable element needs an accessible name to be assigned to it. | |
.k-editor.k-readonly div[contenteditable=false] | aria-readonly=true | Attribute is rendered only when the Editor is readonly. |
Editor with contenteditable div
When in its inline mode (with a contenteditable div element), the editor does not represent a form input. Hence, no additional attributes are required in that scenario.
