Placement
A title is located at the top or bottom of a layout and is either center or flush left,
though occasionally you will see it flush right. If placed inside an architect’s margin
element box (see the Margins section), it is generally shown at the top of the box,
centered, or in the case of a vertical right‑hand box, flush left. The diagrams in
Figure 3.2 show some title placement options. The title is depicted in these diagrams
as a gray bar.
