 ### Input
 
 How is the user input handled in the containers? Should there be active
 containers? Some input may happen for a specific container (i.e. when using
 mouse input). How would I handle scrolling for outer and inner elements of
 a container?

+### Archive
+
+The alignment and sizing options only make sense if both are available. For
+this the current implementation has the viewport size and the content size too
+linked. Therefore they have both been removed (at least for now):
