Content objects Overlay for whole page
You must have seen this notice.
Element for displaying a freely editable layer that overlays a specific page with an adjustable time delay.
This function can - if desired - be inherited by all pages below. If cookies are activated, the webiste remembers that the layer has been clicked away and does not display it on a new page visit (until the cookie is deleted).
The feature is useful for displaying warnings, forcing consent, but also for asking users to participate in surveys or to give ratings.
This feature does not require an extension.
This feature has already been used in the TYPO3 versions:
