Accessibility is achieved in the range navigator control through WAI-ARIA standard. The range navigator features can be effectively accessed through assistive technologies such as screen readers.
WAI-ARIA (Accessibility Initiative – Accessible Rich Internet Applications) defines a way to increase the accessibility of web pages, dynamic content, and user interface components developed with AJAX, HTML, JavaScript, and related technologies. ARIA provides additional semantics to describe the role, state, and functionality of web components.
The following ARIA attributes are used in the range navigator:
Element | Default description |
Selected Area | Reads range selector data points length |
