Accessibility is achieved in the Grid component through WAI-ARIA Standard and Keyboard Navigations. User can effectively access the Grid features 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 list of ARIA attributes is used in Grid.
