This section describes high contrast mode. You can identify sessions as optimized for high contrast in Websheet and Database applications. By default, sessions are not flagged as running in high contrast mode.
Enabling high contrast mode results in the following behavior:
Application Express Websheet runtime.
Websheet application replace CSS-based image links with text links. These text links are only created for images where the source image is transparent and the CSS background property is used in its place.
Custom Database Applications.
Nothing is done natively from the framework. It is up to each developer to provision the mode and make changes where required.
