ARIA attributes

The web accessibility makes web content and web applications more accessible for people with disabilities. Mostly, it helps in dynamic content change and development of advanced user interface controls with AJAX, HTML, JavaScript, and related technologies. The ProgressButton provides a built-in compliance with WAI-ARIA specifications. The WAI-ARIA support is achieved using the aria-label, aria-valuemin, aria-valuemax, and aria-valuenow attributes in the ProgressButton. It helps by providing information about the widget for assistive technology in the screen readers.

aria-label Indicates the text content of the ProgressButton.
