Use of Redundant ARIA roles
Jump to navigation Jump to search
Generally redundant roles are discouraged. In some rare cases there may be a need to use a redundant role.
- Form with role=form will treat the form as a landmark.
- Img with role=img allows hiding of non-labeled child svg elements when img src references an svg element
- List with role=list is used on iOS with list-style-type:none to ensure VO speaks numbered list items
