Accessibility is achieved in the Pager component through WAI-ARIA standard and keyboard navigations. The Pager features can be effectively accessed through assistive technologies such as screen readers.
WAI-ARIA
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 Pager:
