Though not explicitly CSS related, the Accessible Rich Internet Application
(WAI-ARIA) specification ( ) provides
definitions of common semantics of application widgets and states as
a semantic layer to be added to existing HTML markup using the role
attribute. Role types include navigation , progressbar , alertdialog ,
tab, and tooltip . By applying these roles to HTML elements, screen
readers and other assistive devices can react to these items more appro-
priately than they would an element with a class or id of progressbar .
