ARIA attributes

The web accessibility makes web content and web applications more accessible for people with disabilities. It especially helps in dynamic content change and development of advanced user interface controls with AJAX, HTML, JavaScript, and related technologies. The breadcrumb provides a built-in compliance with WAI-ARIA specifications. The WAI-ARIA support is achieved using the attributes such as aria-labeland aria-disabled.
