Try this program. Notice that the HBox has a background color of blue and
the VBox is transparent. You'll see that "Block 1a" placed in the VBox which
is in the HBox displays in blue since it and its container are transparent,
while all of the other blocks display in their specified color. Does this
help explain the use of "transparent"?
