Accessibility

The web accessibility makes web content and web applications more accessible for disabled people. It especially helps in dynamic content change and development of advanced user interface controls with AJAX, HTML, JavaScript, and related technologies.

Calendar provides built-in compliance with WAI-ARIA specifications. WAI-ARIA support is achieved through attributes like aria-label, aria-selected, aria-disabled, and aria-activedescendant applied for navigation buttons, and disable and active day cells.

It helps disabled persons by providing information about the widget for assistive technology in the screen readers. Calendar component contains grid role and grid cell for each day cell.

  • Aria-label: This attribute provides text labels for an object for the previous and next month’s elements. It helps the screen reader object to read.

  • Aria-selected: Indicates the currently selected date of the Calendar component.

  • Aria-disabled: Indicates the disabled state of the Calendar component.

  • Aria-activedescendent: Helps in managing the current active child of the Calendar component.

  • Role: Gives information to assistive technologies about how to handle each element in a widget.

  • Grid-cell: Defines the individual cell that can be focussed and selected.
