Severity

Warning

Messages

This web application contains JavaScript method/property/event [METHOD_NAME]() which will not work in {OSKeyFull} (File: [FILE_NAME]). 
This web application contains CSS property [PROPERTY_NAME] which will not work in {OSKeyFull} (File: [FILE_NAME]). 

Background

Using the fullscreen API, we can direct a user’s attention to specific elements while hiding distracting backgrounds or other apps. The prefixed API works in Internet Explorer 11 and the unprefixed API is intended for Microsoft Edge and beyond.

Resolution

The web application should be re-engineered to use the appropriate API.
