Container visibility is a useful feature to time-restrict certain content on a page.
Access edit page mode by clicking "Edit Page" > click the container's ...-menu > choose Schedule visibility > Set your preferred times and save the changes.
Container visibility can be scheduled to start and/or end at a selected time.
Selecting only the starting time
If you only set the starting time for the scheduled visibility, the container will be hidden until that time. After the visibility starts, the container will always be visible.
Selecting only the ending time
If you choose to only set the ending time for the scheduled visibility, the container will be shown until that time. After the visibility ends, the container will always be hidden. The container can still be accessed and edited in the edit page mode, for example, to make it visible again.
Selecting both times
Selecting both times makes the container to be hidden until the starting time and hidden again after the ending time.
