The Kendo UI for Vue RangeSlider component is [WCAG 2.1 AAA](https://www.w3.org/TR/WCAG21/) and [Section 508](http://www.section508.gov/) compliant. The component also follows the [WAI-ARIA best practices](https://www.w3.org/WAI/ARIA/apg/) for implementing the keyboard navigation for its component role, and is tested against the popular screen readers.

## Wai-Aria

[Slider accessibility specification]({{slider_a11y_link}})


The two focusable elements of the RangeSlider must implement the specification for the **Slider** component. Here is just one clarification for the use of `aria-valuetext` attribute:

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| .k-draghandle | `aria-valuetext` | Specifies the text that would be announced based on the currently selected values in both handle elements (e.g. `aria-valuetext="10 - 50"`). |
