Technique F92:Failure of Success Criterion 1.3.1 due to the use of role presentation on content which conveys semantic information
Applicability
HTML and XHTML
This technique relates to 1.3.1: Info and Relationships (Failure).
Description
This failure occurs when a role of presentation is applied to an element whose purpose
is to convey information or relationships in the content. Elements such as table
, can convey information about the content contained in them via their semantic markup.
The WAI-ARIA role of
presentation
on the other hand, is intended to suppress semantic information of content from the
accessibility API and prevent user agents from conveying that information to the user.
Use of the presentation
role for content which should convey semantic information may prevent the user from
understanding that content.
Examples
Example 1
In this example, tabular data is marked up with role=presentation. Though design layout tables can be marked up in such a way, data tables need to retain their semantic information and should therefore not be marked up with role=presentation.
Example Code:
<table role="presentation"> <caption>Fruits and their colors</caption> <tr> <th>Name</th> <th>Color</th> </tr> <tr> <td scope="row">banana</td> <td>yellow</td> </tr> <tr> <td scope="row">orange</td> <td>orange</td> </tr> </table>
