Interface HeadingRole

All Superinterfaces:
RoletypeRole, SectionheadRole, StructureRole
All Known Implementing Classes:
HeadingRoleImpl
public interface HeadingRole
extends SectionheadRole

HeadingRole interface. The interface defines methods for setting, getting, removing states and properties.

Allows ARIA Accessibility attributes to be added to widgets so that they can be identified by assistive technology.

ARIA roles define widgets and page structure that can be interpreted by a reader application/device. There is a set of abstract roles which are used as building blocks of the roles hierarchy structural and define the common properties and states for the concrete roles. Abstract roles cannot be set to HTML elements.

There are states and properties that are defined for a role. As roles are organized in a hierarchy, a role has inherited and own properties and states which can be set to the element.

For more details about ARIA roles check The Roles Model .
