WAI-ARIA roles in a screen layout

Version:

Only available versions of this content are shown in the dropdown

Screen readers use WAI-ARIA roles to determine what kind of content a layout holds. In Pega Platform, screen layouts have WAI-ARIA roles assigned by default, which improves the accessibility of your application.

The following table lists the areas in a screen layout, the corresponding auto-generated HTML tags, and the WAI-ARIA roles that are assigned to those areas by default.

For more information on screen layouts, see Configuring a screen layout.
