The workspace is indicated by the solid black line that runs even with:

• The top and bottom edges of the topmost and bottommost container items

• The left and right edges of the leftmost and rightmost container items

The workspace is defined by the minimum and maximum x- and y-coordinates of the items in the container. The work area of the container window can be scrolled only within the workspace and only as far as is necessary to see the topmost, bottommost, leftmost, and rightmost container items.
