These states are represented graphically in
three different ways:
- The appearance of the object base changes (hatched around the perimeter, flat base, or base in relief).
- An icon appears in the top left corner of the object base.
- Both changes occur.
The table illustrates these changes on a
node element. The same graphical representations are used for
links, groups, and cards. Note that the primary state of empty
slots is not represented graphically.
