Refer to our accessibility demos, where accessibility level and compliance of the Kendo UI components can be tested.
In terms of web components, accessibility means that the websites and applications provide full control over their features by enabling users with disabilities to access them through assistive technologies such as screen readers.
Assistive technologies work well for the most basic and text-driven websites and applications. However, the Web is dynamically changing and is now well beyond the realm of text-based experiences. As a result, assistive technologies struggle to keep up.
Web developers can do a lot to bridge this gap between the current challenges which web applications pose to disabled users and the capabilities which assistive technologies support. By providing features, such as full keyboard support, high-contrast visual elements, and text-based equivalents of non-text elements, and by adhering to standards like WAI-ARIA, WCAG 2.1, and Section 508, developers deliver completely accessible and rich Internet applications.
The Kendo UI for jQuery components are highly extensible and customizable. Depending on the level of customization applied, you may be introducing rendering that is not accessible. Therefore, it is recommended that web developers test any modifications and templates they create to ensure the components still meet the desired level of accessibility standards. Additionally, be mindful of components working with custom input (images, text, HTML content, and so on) and make sure your content is accessible, too.
