Section 508 Support

Section 508 is a set of standards ensuring that all users, regardless of their disability status, are able to access technology.

These standards apply to electronic and information technology and contain technical criteria specific to various types of technologies and performance-based requirements which focus on functional capabilities of covered products.

The following table is based on the Voluntary Product Accessibility Template (VPAT) requirements. It provides detailed explanation about the accessibility features Kendo UI delivers according to the Section 508 Web content standards.

Here you can download the latest version of the VPAT Template, describing the Kendo UI for jQuery accessibility compliance state.

Table 1. Section 1194.22 Web Information and Application Standards

Criteria Supporting features Remarks
(a) A text equivalent for every non-text element shall be provided—for example, through "alt", "longdesc", or in the element content. Supports All images (img HTML elements) used by Kendo UI have their alt attribute set. If developers use images in Kendo UI templates, they have to set the "alt" or "longdesc" attribute in the template definition.
(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. Supports Kendo UI ships the MediaPlayer widget.
(c) Web pages shall be designed so that all information conveyed with color is also available without color—for example, from context or markup. Supports Kendo UI widgets make sure that apart from color information is conveyed by other means too.
(d) Documents shall be organized so they are readable without requiring an associated style sheet. Supports with exceptions Kendo UI widgets work without an applied stylesheet. Some widgets with rich UI, such as the Scheduler and Gantt, do not look as good as designed. Point (d.2) is not supported at all, because inline HTML styles, set by JavaScript, are still needed to ensure the correct rendering.
(e) Redundant text links shall be provided for each active region of a server-side image map. Supports Kendo UI does not use image maps.
(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. Supports Kendo UI does not use image maps.
(g) Row and column headers shall be identified for data tables. Supports with exceptions The Kendo UI widgets use attributes to identify the column headers. The Pivot and Scheduler are exceptions that will be addressed by a future update.
(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. Supports
(i) Frames shall be titled with text that facilitates frame identification and navigation. Supports
(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. Supports Kendo UI does not cause screen flicker with a frequency greater than 2 Hz and lower than 55 Hz.
(k) A text-only page with equivalent information or functionality shall be provided to make a website comply with the provisions of this part when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes. Not applicable Developers are responsible for providing text-only content for pages that use Kendo UI.
(l) When pages utilize scripting languages to display content or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology. Supports Kendo UI is a JavaScript framework and cannot operate when JavaScript is disabled. Kendo UI provides keyboard navigation support and screen reader support through WAI-ARIA attributes.
(m) When a web page requires that an applet, plugin, or other application be present on the client system to interpret page content, the page has to provide a link to a plugin or applet that complies with §1194.21(a) through (l). Supports Kendo UI does not use any external plugins or applets.
(n) When electronic forms are designed to be completed online, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supports with exceptions Most forms in Kendo UI are accessible to assistive technologies with some exceptions that will be addressed by a future update.
(o) A method shall be provided that permits users to skip repetitive navigation links. Supports Kendo UI does not provide a "skip navigation link" but instead offers keyboard shortcuts to most of the features in the user interface.
(p) When a timed response is required, the user shall be alerted and given sufficient time to indicate that more time is required. Supports Kendo UI does not require a timed response as part of its core functionality.
